Somali militant group al-Shabaab have admitted being behind an attack on a Kenyan quarry site which killed dozens.
The group said its fighters had killed 40 people, although the government and other officials put the death toll at 36.
Village elders said at least two non-Muslims, who were attacked as they slept, were beheaded while the rest were shot at close range.
In a statement, al-Shabaab said it had executed dozens of "Kenyan crusaders" as punishment for Kenya sending troops to Somalia to fight Islamist rebels.
