Kenya: 2 quarry workers killed in suspected extremist attack

A Kenyan government official says two quarry workers have been shot dead and one is missing in a suspected extremist attack in the northern county of Mandera.

Regional Coordinator Mohamud Saleh said Friday the attack took place in the town of Elwak. Saleh says workers had been asked to leave the site because Somalia-based al-Shabab fighters had been seen in the area a few days earlier.

Mandera is next to the Somali border and has been hardest hit in recent years by an al-Shabab campaign to avenge Kenyan troop presence in Somalia since 2011.

Kenya has managed to stop the frequency of attacks in the capital and major towns. But human rights groups say the government uses methods such as extrajudicial killings that can fuel revenge attacks.
