One woman was on Monday killed and three others injured following a gas cylinder explosion in Eastleigh, Nairobi.
The middle-aged woman was hit by an object as she escaped from the scene of the explosion at about 4 pm, police said.
Three other people were rushed to the hospital with multiple injuries following the explosion.
Police said they are investigating the incident.
The residents said the blast was loud because of the nature of damage it caused in one of the houses.
Doors were shattered, windows damaged and household goods turned upside down by the blast heard several meters away.
There was casualty evacuation from the scene but officials said only three of them had serious injuries.
Nairobi police boss Adamson Bungei said preliminary findings had shown it was a gas leak that caused the blast.
“For now we suspect a gas leak. Someone left the gas leaking and another came and lit it causing the blast,” he said.
“Experts are on the ground and have confirmed the blast was caused by the gas cylinder.”
Bomb experts surrounded the building and combed it before walking out.
They later declared it had been caused by a gas cylinder.
Residents watched from a distance as the experts worked on the scene.
Police said they were waiting for the owner of the house for questioning.
