Gunmen have killed some 36 quarry workers near the north Kenyan town of Mandera, near the border with Somalia, police say.
The attack on the quarry workers took place early on Tuesday. Witnesses said the victims were caught after midnight, while sleeping in their tents at the quarry.
A local police chief said the assailants targeted non-Muslim workers at the quarry in Kormey, 15km (nine miles) from Mandera town.
Kenya’s Red Cross said on its Twitter feed that security personnel and one of its own teams were on the ground at the site of the attack.
Reuters news agency quoted one witness as saying that most of the victims had been shot in the head, and four had been beheaded.
No group has so far said it carried out either of the attacks, both of which occurred close to the border with Somalia.
