A gas truck exploded in Kenya's capital Nairobi, sending a huge fireball into the night sky and causing a blaze that killed at least three people and injured more than 200, authorities and first responders said on Friday.
Residents in a nearby building screamed as a column of flame shot hundreds of feet into the air just before midnight, briefly forming a mushroom cloud, video posted on social media and verified by Reuters showed.
The government said three people had died in the explosion at a gas refilling plant and 280 more were being treated at hospitals around Nairobi. The Kenyan Red Cross said others were being treated at a triage point.
The fire engulfed a nearby textile and garment warehouse, while damaging several vehicles and commercial and residential properties, the government said.
A Reuters picture from the scene of the fire showed smoke billowing from several burning houses nearby.
Kenya's Energy and Petroleum Regulatory Authority (EPRA) said last year it had rejected three applications for construction permits for a Liquefied Petroleum Gas (LPG) storage and refilling plant at the site of the explosion because of the high population density around it.
EPRA said it had asked the applicant to submit a risk assessment "indicating the radiation blast profiles in the unfortunate case of an explosion" but that this was never done.
It was not immediately clear who owned the site.
