Nigerian Islamist group Boko Haram has told us at the BBC it carried out the series of bombings after President Goodluck Jonathan's inauguration on Sunday.
The worst incident was at an army barracks in the northern city of Bauchi in which at least 14 people died.
A sect spokesman said it was also responsible for killing the brother of the Shehu of Borno, one of Nigeria's most important Islamic leaders.
The sect has been behind numerous recent assassinations in Borno state.
It is opposed to Western education and accuses Nigeria's government of being corrupted by Western ideas.
Clashes in Borno's state capital, Maiduguri, between the Boko Haram and the police in July 2009 left hundreds of people dead, mainly members of the sect.
For the past eight months, sect members have been fighting a guerrilla war in Borno, killing policemen and people they believe were helping the security services in the fight against them.
Sect spokesman Abu Zayd told the BBC's Hausa Service that the group was behind the bombings on Sunday.
''We are [also] the ones responsible for the killing of the junior brother of the Shehu of Borno," he said.
Abba Anas Ibn Umar Garbai was killed by gunmen outside his home in Maiduguri on Monday evening.
The Shehu of Borno is one of Nigeria's most prominent religious figures - second only to the Sultan of Sokoto, the spiritual leader of Nigeria's Muslims.
"As we always say, these traditional institutions are being used to track and hunt us, that is why we attack them," Mr Zayd said.
"We are doing what we are doing to fight injustice, if they stop there satanic ways of doing things and the injustices, we would stop what we are doing.''
Officials say 16 people died in the explosions in Bauchi, Zuba, Zaria, hometown of Vice-President Namadi Sambo, and Maiduguri.
The first attack came only hours after President Jonathan was sworn in for his first full four-year term of office in the capital, Abuja.
Mr Jonathan was promoted from vice-president after northerner Umaru Yar'Adua died in office in 2010.
April's election was largely considered free and fair, but hundreds of people were killed in three days of rioting and reprisal killings in northern towns following the announcement of the result.
Mr Jonathan, a southerner, secured nearly 60% of the vote in the election. His main challenger, northern Muslim and former military ruler Muhammadu Buhari, came a distant second with almost 32%.
Nigeria is divided by rivalry between the predominantly Muslim north and the mainly Christian south, which also have cultural, ethnic and linguistic differences.
Analysts say that Mr Jonathan will have to tackle this north-south rivalry and also the simmering tension in the oil-producing Niger Delta.
To win at the first round, a candidate not only needs the majority of votes cast, but at least 25% of the vote in two-thirds of Nigeria's 36 states. Goodluck Jonathan, of the PDP, reached that threshold in 31 states; runner-up Muhammadu Buhari of the CPC only did so in 16 states.
Nigeria's 160 million people are divided between numerous ethno-linguistic groups and also along religious lines. Broadly, the Hausa-Fulani people based in the north are mostly Muslims. The Yorubas of the south-west are divided between Muslims and Christians, while the Igbos of the south-east and neighbouring groups are mostly Christian or animist. The Middle Belt is home to hundreds of groups with different beliefs, and around Jos there are frequent clashes between Hausa-speaking Muslims and Christian members of the Berom community.
Despite its vast resources, Nigeria ranks among the most unequal countries in the world, according to the UN. The poverty in the north is in stark contrast to the more developed southern states. While in the oil-rich south-east, the residents of Delta and Akwa Ibom complain that all the wealth they generate flows up the pipeline to Abuja and Lagos.
Southern residents tend to have better access to healthcare, as reflected by the greater uptake of vaccines for polio, tuberculosis, tetanus and diphtheria. Some northern groups have in the past boycotted immunisation programmes, saying they are a Western plot to make Muslim women infertile. This led to a recurrence of polio, but the vaccinations have now resumed.
Female literacy is seen as the key to raising living standards for the next generation. For example, a newborn child is far likelier to survive if its mother is well-educated. In Nigeria we see a stark contrast between the mainly Muslim north and the Christian and animist south. In some northern states less than 5% of women can read and write, whereas in some Igbo areas more than 90% are literate.
Nigeria is Africa's biggest oil producer and among the biggest in the world but most of its people subsist on less than $2 a day. The oil is produced in the south-east and some militant groups there want to keep a greater share of the wealth which comes from under their feet. Attacks by militants on oil installations led to a sharp fall in Nigeria's output during the last decade. But in 2010, a government amnesty led thousands of fighters to lay down their weapons.
Syrian President Bashar al-Assad should face trial at a UN court over the "brutal" treatment of his people, Australia's foreign minister says.
Kevin Rudd said incidents such as the alleged torture and murder of a 13-year-old boy by security forces had robbed Mr Assad of any legitimacy.
President Assad invited the boy's family to meet him and promised an inquiry, state television said.
Activists say more than 1,000 people have died in weeks of protests.
The 13-year-old boy, Hamza al-Khatib, has become an icon of the anti-government uprising in Syria, says the BBC's Jim Muir.
Activists say he was detained by security forces and tortured to death, while the authorities insist he was shot dead during a demonstration.
Mr Rudd called it a "brutal act" and accused Mr Assad of taking "large-scale directed action" against his own people.
"I believe it is high time that the Security Council now consider a formal referral of President Assad to the International Criminal Court," said Mr Rudd.
Martyr to both sides
US Secretary of State Hillary Clinton said the boy's death showed the regime was deaf to the voice of its people.
Clinton: "I hope this child did not die in vain but that the Syrian government will end the brutality and begin a transition to real democracy"
"I can only hope that this child did not die in vain but that the Syrian government will end the brutality and begin a transition to real democracy," she said.
Hamza Khatib is being hailed as a martyr, and his picture is now held aloft at demonstrations around the country and abroad.
He is being compared to the Tunisian market-seller Mohamed Bouazizi and Iranian pro-democracy protester Neda Agha Soltan whose deaths galvanised anti-government campaigns.
Hamza is also being called a martyr by the Syrian authorities.
State TV said the teenager's father and family were invited to meet President Assad, and they were quoted as saying he "engulfed us with his kindness and graciousness".
A man who identified himself as Hamza's father said: "The president considered Hamza his own son and was deeply affected."
'Mutilated body'
The boy went missing after a demonstration at an army barracks near Deraa in the south at the end of April.
Activists say he was captured and tortured to death, and that his mutilated body was handed back to his family four weeks later.
The government says he received three fatal gunshot wounds during the protest and died on the spot, but there was a delay in handing over his body because he was not identified.
Syrian state TV aired a programme about the teenager on Tuesday night in which a judge said death was due to "a number of bullet wounds without any indication of torture or beating on the body".
Coroner Akram al-Shaar blamed the state of the body on decomposition, adding: "There are no marks on the surface of the body that show violence, resistance or torture."
Human Rights Watch (HRW) published a report on Wednesday that said "systematic killings and torture by Syrian security forces" in Deraa could qualify as crimes against humanity.
"For more than two months now, Syrian security forces have been killing and torturing their own people with complete impunity," said Sarah Leah Whitson, HRW Middle East director.
"They need to stop - and if they don't, it is the Security Council's responsibility to make sure that the people responsible face justice."
Thousands of Syrian refugees have fled into northern Lebanon bringing with them tales of brutality by Syrian security forces in the town of Tal Kalakh, the BBC's Owen Bennett-Jones reports.
The US is working on a plan to categorise cyber-attacks as acts of war, says the New York Times newspaper.
In future, a US president could consider economic sanctions, cyber-retaliation or a military strike if key US computer systems were attacked, officials have said recently.
The planning was given added urgency by a cyber-attack last month on the defence contractor, Lockheed Martin.
A new report from the Pentagon is due out in a matter of weeks.
"A response to a cyber-incident or attack on the US would not necessarily be a cyber-response. All appropriate options would be on the table," Pentagon spokesman Colonel Dave Lapan told reporters on Tuesday.
'All necessary means'
The Pentagon's planning follows an international strategy statement on cyber-security, issued by the White House on 16 May.
The US would "respond to hostile acts in cyberspace as we would to any other threat to our country", stated the White House in plain terms.
"We reserve the right to use all necessary means - diplomatic, informational, military, and economic - as appropriate and consistent with applicable international law, in order to defend our nation, our allies, our partners and our interests."
The strategy will classify major cyber-attacks as acts of war, paving the way for possible military retaliation, reported The Wall Street Journal after interviewing defence officials.
Sophistication of hackers
One of the difficulties strategists are grappling with is how to track down reliably the cyber-attackers who deliberately obscure the origin of their incursions.
And it is not clear how the Pentagon proposes to deal with cyber-attackers, such as terrorists, who are not acting for a nation state.
The sophistication of hackers and frequency of the attacks came back into focus after an attack on arms-maker Lockheed Martin on 21 May.
Lockheed said the "tenacious" cyber-attack on its network was part of a pattern of attacks on it from around the world.
The US defence department estimates that more than 100 foreign intelligence organizations have attempted to break into American networks.
US military prosecutors have filed new charges against self-described 9/11 mastermind Khalid Sheikh Mohammed and four alleged co-conspirators held at Guantanamo Bay, reports say.
The charges are expected to be formally unveiled later on Tuesday.
All five defendants had previously been charged at Guantanamo over the attacks.
But the charges were set aside as the Obama administration tried to move the trial into US civilian courts, a move which was reversed in April.
Mohammed previously admitted to being responsible "from A to Z" for the attacks in New York and Washington.
Mohammed was captured in Pakistan in March 2003 and sent to the US detention centre in Cuba in 2006.
Ratko Mladic is being flown from Belgrade to a UN tribunal in The Hague, after a Serbian court rejected an appeal against his transfer.
Serbia's justice minister said she had signed the extradition order. After the hearing, the former Bosnian Serb army chief was taken to the airport.
He faces genocide charges over the Bosnian conflict in the 1990s.
His lawyer had argued he was too ill to be tried. But doctors said he was fit enough to be extradited.
The 69-year-old was seized last Thursday in Lazarevo village, north of Belgrade, having been on the run for 16 years.
On Tuesday, a Belgrade court ruled that Gen Mladic was fit enough to be handed over to the International Criminal Tribunal for the former Yugoslavia (ICTY) in The Hague.
Later, a police convoy was seen leaving the court building, raising speculation that the defendant was already on his way.
Serbian Justice Minister Snezana Malovic then announced she had signed the extradition papers and that Gen Mladic was already on the plane.
Omarska concentration camp victim Kamal Pervanic: "My guards were my former teachers"
Earlier on Tuesday, Gen Mladic had been allowed to visit the grave of his daughter Ana, albeit under heavy security.
Ana Mladic committed suicide in 1994 aged 23, reportedly shooting herself with her father's favourite pistol after she read about his alleged crimes in a magazine.
During the 20-minute visit to her grave, Gen Mladic lit a candle and he left a small white bouquet of flowers with a red rose in the middle, said Serbia's deputy war crimes prosecutor, Bruno Vekaric.
Gen Mladic's arrest is considered crucial to Serbia's bid to join the European Union.
His son Darko Mladic said his father had told him he was not responsible for the killings in Srebrenica, committed after Bosnian Serb troops overran the town in July 1995.
The former Yugoslavia was a Socialist state created after German occupation in World War II and a bitter civil war. A federation of six republics, it brought together Serbs, Croats, Bosnian Muslims, Albanians, Slovenes and others under a comparatively relaxed communist regime. Tensions between these groups were successfully suppressed under the leadership of President Tito.
After Tito's death in 1980, tensions re-emerged. Calls for more autonomy within Yugoslavia by nationalist groups led in 1991 to declarations of independence in Croatia and Slovenia. The Serb-dominated Yugoslav army lashed out, first in Slovenia and then in Croatia. Thousands were killed in the latter conflict which was paused in 1992 under a UN-monitored ceasefire.
Bosnia, with a complex mix of Serbs, Muslims and Croats, was next to try for independence. Bosnia's Serbs, backed by Serbs elsewhere in Yugoslavia, resisted. Under leader Radovan Karadzic, they threatened bloodshed if Bosnia's Muslims and Croats - who outnumbered Serbs - broke away. Despite European blessing for the move in a 1992 referendum, war came fast.
Yugoslav army units, withdrawn from Croatia and renamed the Bosnian Serb Army, carved out a huge swathe of Serb-dominated territory. Over a million Bosnian Muslims and Croats were driven from their homes in ethnic cleansing. Serbs suffered too. The capital Sarajevo was besieged and shelled. UN peacekeepers, brought in to quell the fighting, were seen as ineffective.
International peace efforts to stop the war failed, the UN was humiliated and over 100,000 died. The war ended in 1995 after NATO bombed the Bosnian Serbs and Muslim and Croat armies made gains on the ground. A US-brokered peace divided Bosnia into two self-governing entities, a Bosnian Serb republic and a Muslim-Croat federation lightly bound by a central government.
In August 1995 the Croatian army stormed areas in Croatia under Serb control prompting thousands to flee. Soon Croatia and Bosnia were fully independent. Slovenia and Macedonia had already gone. Montenegro left later. In 1999 Kosovo's ethnic Albanians fought Serbs in another brutal war to gain independence. Serbia ended the conflict beaten, battered and alone.

Following the arrest of former Bosnian Serb leader Radovan Karadzic in 2008, Gen Mladic became the most prominent Bosnian war crimes suspect still at large.
He was indicted by the UN war crimes tribunal in The Hague in 1995 for genocide over Srebrenica - the worst single atrocity in Europe since World War II - and other alleged crimes.
Having lived freely in the Serbian capital, Belgrade, he disappeared after the arrest of former Yugoslav President Slobodan Milosevic in 2001.
On Sunday, thousands of people rallied in Belgrade against his arrest, hailing the general as a Serbian national hero and decrying the pro-Western government of President Boris Tadic for arresting him.
Gen Martin Dempsey has been nominated as the new chairman of the joint chiefs of staff, the highest US military post.
A veteran of the Iraq war, Army Chief of Staff Dempsey will succeed Navy Admiral Mike Mullen as the president's top military adviser on 30 September.
President Obama made the announcement in the White House garden but it is subject to Senate approval.
Obama has also named Adm James Winnefeld, the head of the US Northern Command, to serve as vice chairman.
Gen Ray Odierno was nominated to replace Gen Dempsey as the Army's chief of staff.
In naming Gen Dempsey, the president described him as "one of our nation's most respected and combat-tested generals".
If confirmed by the Senate, the general would be the top adviser as the scaling down of US forces in Iraq continues and troops in Afghanistan begin to come home later this year.
The BBC's Jonny Dymond, in Washington, says General Dempsey is understood to be wary of hi-tech projections of future military needs; his experience in counter insurgency has led him to place a premium on boots on the ground.
But his biggest challenge may be more prosaic, our correspondent adds. Defence consumes around 20% of the federal budget and from across the political spectrum there is a demand for cuts.
Time in combat
General Dempsey would be involved in establishing priorities for cutting the defence budget, working with the incoming Defence Secretary Leon Panetta, an appointment that also requires confirmation from the Senate.
Dempsey only just began his four-year tenure as Army chief of staff in April, but he has extensive experience.
His time in combat includes serving as the commander of the 1st Armoured Division in Baghdad in 2003 and helping to train Iraqi security forces in another tour.
He also served as acting commander of the US Central Command, overseeing US military operations in the Middle East, Persian Gulf and Central Asia.
Defence Secretary Robert Gates, who retires this year, praised all three appointments.
He said: "They possess the right mix of intellectual heft, moral courage, and strategic vision required to provide sound and candid advice to the president and his national security team."
The Joint Chiefs of Staff (JCS) is based at the Pentagon in Virginia and advises the secretary of defence, the Homeland Security Council, the National Security Council and the president on military matters.
Ex-Bosnian Serb army chief Ratko Mladic has been declared fit to be extradited from Serbia to face trial in The Hague.
Court spokeswoman Maja Kovacevic said the transfer conditions had been met.
Gen Mladic's legal team say he is in poor health and that they will appeal on Monday. They have requested that he be admitted to hospital over concerns about his health.
Gen Mladic, arrested on Thursday after 16 years on the run, faces genocide charges over the 1992-95 Bosnian war.
He was indicted in 1995 over the killings about 7,500 Bosnian Muslim men and boys that July at Srebrenica - the worst single atrocity in Europe since World War II - and other crimes.
Assessment call
Judge Kovacevic told reporters outside the court that Gen Mladic's health was good enough for him to be tried at the UN International Criminal Tribunal to the former Yugoslavia in The Hague.
"It has been certified that Ratko Mladic is healthy enough to take part in that [extradition], because all medical examinations have been carried out and we got an assessment that he's capable, despite the fact that he suffers from a number of chronic conditions."
He had refused to accept a copy of the tribunal's indictment, she added. After this, the court ruled that the conditions for his transfer had been met and he was given until Monday to appeal.
The wide, tree-lined village streets were quiet in the early morning sun, as farm workers on old bikes stopped to look at the police guard outside 2 Vuk Karadzic Street, the house where Ratko Mladic was found. One policemen, who told us he lived four doors down, said he'd never seen Gen Mladic.
Other locals say the same. The home itself is like any other on the street - a small cottage with a broken-down car in the yard and an ancient tractor, its damaged doors swinging in the wind.
Trying to film the house provoked an angry response. A man flew out swearing with fists raised - we later learned he was Gen Mladic's nephew. Some in the close-knit village were vocal in their support of their hidden neighbour, reflecting a deep sense that the world's view of the Balkans war was unfair.
Defence lawyer Milos Saljic confirmed that an appeal would be submitted on Monday. The BBC's Mark Lowen, outside the court, says this makes it unlikely he would leave Serbia before Tuesday.
Gen Mladic's wife Bosiljka and their son Darko turned up at the court to visit him. Mr Saljic later said this was their first meeting with him in 10 years.
Darko told journalists his father was innocent and not in a fit state to be sent to The Hague.
He said the family was asking for an assessment of his health by independent experts, including some from Russia.
Gen Mladic had an electrocardiogram heart test and a brain scan, which revealed two scars from cerebral haemorrhages, Darko Mladic added.
Our correspondent says Mrs Mladic only recently said she thought her husband was dead.
Having lived freely in the Serbian capital, Belgrade, Gen Mladic is believed to have gone into hiding after the arrest of former Yugoslav President Slobodan Milosevic in 2001.
Following the detention of former Bosnian Serb political leader Radovan Karadzic in 2008, Gen Mladic became the most prominent Bosnian war crimes suspect at large.
The arrest was hailed internationally.
On Thursday, Serbian TV showed footage of the former general wearing a baseball cap and walking slowly as he appeared in court in Belgrade for the first time.

Protests
Reports in Serbian media suggested that one of Gen Mladic's arms was paralysed, which was probably the result of a stroke.
Serbia had been under intense international pressure to arrest Gen Mladic and send him to the Hague tribunal.
After the arrest, the government banned public gatherings in an effort to prevent any pro-Mladic demonstrations.
But hundreds of ultra-nationalists clashed with police in the northern city of Novi Sad, and there was a smaller demonstration involving several dozen protesters in the centre of Belgrade.
The government is now keen for a speedy extradition of Gen Mladic, whom Serb nationalists still regard as a hero, our correspondent says.
President Boris Tadic said Gen Mladic's arrest had brought Serbia and the region closer to reconciliation, and opened the doors to European Union membership.
'Stake-out'
Mr Tadic rejected criticism that Serbia had been reluctant to seize Gen Mladic.
A spokeswoman for families of Srebrenica victims, Hajra Catic, told AFP news agency: "After 16 years of waiting, for us, the victims' families, this is a relief."
Gen Mladic was seized in the province of Vojvodina in the early hours of Thursday, reportedly as he went out into his garden for a pre-dawn walk.
He had two guns with him, but put up no resistance, officials said.
Serbian security sources told AFP news agency that three special units had descended on a house in the village of Lazarevo, about 80km (50 miles) north of Belgrade.
The single-storey house was owned by a relative of Gen Mladic and had been under surveillance for the past two weeks, one of the sources added.
In the latest revelations, police officials told the Associated Press that Gen Mladic had moved to the village two years ago. They also said he admitted his identity immediately in a whisper when found.
AP quoted officials as saying no-one would receive a reward for his arrest, because police were not acting on a tip-off when they arrested him.
Lawyer Milos Saljic told Serbia's B92 news agency that Darko Mladic had visited Lazarevo just a week ago but had no idea his father was there.
Local resident Zora Prodanovic told the BBC: "I'm really surprised. My mother lives four doors down from here and I've never seen him."
"People are shocked, furious, fuming. Our government should stop this bloody business," said another, Momcilo Zivkovic.
"They have arrested our general, who'd defended those who were defenceless; he's now facing false allegations."

Egypt is to open the Rafah border crossing into Gaza permanently to most Palestinians from Saturday, Egyptian state news agency Mena has said.
Gaza has been under blockade since 2007, when the Islamist Hamas movement took control of the territory.
Under ex-President Hosni Mubarak - ousted in February - Egypt opposed the Hamas administration and helped Israel to enforce the blockade.
Israel says the blockade is needed to stop weapons being smuggled into Gaza.
The Rafah crossing will be opened permanently from 0900 to 2100 every day except Fridays and holidays, beginning Saturday 27 May, Mena said.
"Palestinian women of all ages will be exempted from visas as will men under 18 or over 40," Mena reported.
Rafah is the only crossing into Gaza which bypasses Israel.
Egypt's transitional military government said last month it intended to open the crossing.
The move is likely to anger Israel. Last year, Israel eased restrictions on goods entering Gaza, but significant shortages in the territory remain.
Mena said the decision to open the Rafah crossing was part of efforts "to end the status of the Palestinian division and achieve national reconciliation".
The EU plans to boost development aid and loans for its Arab neighbours in the southern Mediterranean, but the help will be tied to political reform.
The EU foreign policy chief, Baroness Ashton, said 1.24bn euros (£1bn) would be added to the 5.7bn-euro EU "neighbourhood" budget for 2011-13.
The EU is adopting a "more funds for more reform" approach, she said.
The wave of uprisings in the Arab world has forced a major foreign policy rethink in European capitals.
The 27 EU governments - the European Council - support a 1bn-euro increase in European Investment Bank (EIB) lending to the southern Mediterranean for 2011-13.
The European Bank for Reconstruction and Development (EBRD) has also agreed to extend its operations into the Arab world, starting with Egypt. Annual lending volumes could reach around 2.5bn euros by 2013, according to the EU statement released on Wednesday.
Until now the EBRD's focus has been on eastern Europe, where the European Neighbourhood Policy (ENP) has been operating since 2004, fostering closer ties between the EU and 16 partner countries.
The EU plans to help democratise the southern Mediterranean through a European Endowment for Democracy and a Civil Society Facility, European Commission President Jose Manuel Barroso said.
The consolidation of democracy in the region would improve stability, he said.
The EU has financed a range of projects in North Africa in recent years, but they have not been conditional on Arab leaders launching serious political reforms.
The unrest in North Africa this year - especially the war in Libya - has fuelled concerns that Europe could face a new surge in migration from Africa, at a time of economic hardship and high unemployment across the EU.
