At least 14 people have been killed and several others wounded in a gun attack near a military camp at the Kenyan border with Somalia.
It is believed the victims were workers from a local quarry in Mandera county in the north-east of the country.
Residents told the BBC they had heard two explosions, followed by heavy gunfire in the middle of a night.
Militia group al-Shabab, which operates out of Somalia, has confirmed to the BBC it carried out the attack.
Mandera County Commissioner Alex Ole Nkoyo told AFP that people were sleeping when the gunmen struck.
"They just came and hurled explosives in the houses," he said.
Kenya Red Cross said it was sending an aircraft to the scene to fly the injured to hospitals in Nairobi.
