Scores of people have died because of a petrol pipeline explosion that also sparked a fire in Kenya's capital, Nairobi.

The blast took place in the city's Lunga Lunga industrial area, and police and troops cordoned off the area as firefighters battled fierce flames in the surrounding shanty town.

A Red Cross official, Pamela Indiaka, said at least 75 bodies had been recovered. Some reports put the toll at more than 100 dead.

The BBC's correspondent in Nairobi, Kevin Mwachiro, explained what is believed to have started the fire.
