NAIROBI, Kenya — A vehicle loaded with gas exploded and set off an inferno that burned homes and warehouses in Kenya’s capital early Friday, killing at least three people and injuring more than 270, with the death toll expected to rise.

Many residents were likely inside their homes when the fire reached their houses late in the night in the Mradi area of the Nairobi neighborhood of Embakasi, government spokesman Isaac Mwaura said.

The truck explosion ignited a huge fireball, and a flying gas cylinder set off a fire that burned down the Oriental Godown, a warehouse that deals with garments and textiles, Mwaura said. Several other vehicles and businesses were damaged by the inferno that started around 11:30 p.m. Thursday.

At the scene after daybreak, several houses and shops were burned out. The shell of the vehicle believed to have started the explosion was lying on its side. The roof of a four-story residential building about 200 meters (yards) from the scene of the explosion was broken by a flying gas cylinder. Electric wires lay on the ground. Nothing remained in the burned-out warehouse except the shells of several trucks.

Alfred Juma, an aspiring politician, said he heard loud noise from a gas cylinder in a warehouse next to his house. “I started waking up neighbors asking them to leave,” Juma said.

He said he warned a black car not to drive through the area, but the driver insisted and his vehicle stalled because of the fumes. “He attempted to start the car three times and that’s when there was an explosion and the fire spread into the (warehouse) setting off other explosions.”

He said he grabbed two children and they hid in a sewage ditch until the explosions ended. His family had not been present, but Juma lost everything he owned in the fire.

“Police were turning away everyone and so it was difficult to access my house and I had to seek a place to sleep until this morning,” neighbor Caroline Karanja said. She said the smell and smoke were still choking, and she would have to stay away for a while because she had young children.

Police and the Kenya Red Cross reported three deaths. The toll may rise after daybreak, said Wesley Kimeto, the Embakasi police chief.

The government and Red Cross said 271 people were taken to several hospitals with injuries.

The proximity of the industrial company to residences raised questions about enforcement of city plans. Officials at the county government have been accused of taking bribes to overlook building codes and regulations.
