Kenya's Prime Minister, Raila Odinga, describes the scene after a petrol pipeline explosion and fire in Kenya's capital as "shocking".

More than 60 people died in the blast in Nairobi's Lunga Lunga industrial area.

Police and troops cordoned off the district as firefighters battled fierce flames in a nearby shanty town.

A cigarette butt is believed to have started the fire.
