A petrol pipeline has exploded in Nairobi, Kenya killing at least 100 and hospitalising more than 80 people.

The Associated Press has reported that the pipeline, which runs through the crowded slums of Embakasi between the capital city and Nairobi Airport, exploded and caused shacks for 300 metres around the site to burn down.

Victim's bodies have been seen scattered around the site, and some residents were forced to jump into a sewage-filled river after catching on fire.

Local man Joseph Mwego told Agence France-Presse "There was a loud bang, a big explosion, and smoke and fire burst up high…"

Earlier today the pipeline began leaking, and many local people had begun gathering to collect the fuel.
