AT LEAST 14 people have been killed and 11 others injured after a group of armed men attacked quarry workers in northern Kenya, officials said.

The attackers, suspected to be al-Shabab fighters, stormed two plots adjacent to each other in Mandera town and opened fire at people, mostly workers, early yesterday morning.

Al-Shabaab were responsible for the attack, the group’s spokesman told Al Jazeera – adding that they targeted “crusaders” in the attack to “avenge killings of Muslims in Somalia and Kenya by Kenyan security forces”.

“The attack occurred at a village near a large livestock market just outside the town, 14 people are dead,” a senior police officer told reporters.
