Gunmen killed 36 workers in an attack on a quarry in Kenya's Mandera county, which borders Somalia, said the county governor on Tuesday NY Times reports quoting Reuters.
Some 28 people were killed in the area last month when al Shabaab militants hijacked a Nairobi-bound bus, causing widespread anger. Kenya has suffered a string of gun and grenade attacks since it sent troops into Somalia to fight al Shabaab in late 2011.
A Reuters witness at the scene counted 36 bodies at the Korome quarry. All the victims had been shot in the head, except for four who had been beheaded.
The witness said the workers were attacked while sleeping in their tents at the quarry.
