Two Kenyan teachers were killed when suspected al Shabaab militants threw an explosive device at a house at a school in Mandera county near the Somali border, police said.
Al Shabaab claimed responsibility for the attack overnight.
“Last night we killed two non-Muslim Kenyan teachers after we attacked their school in Arabow village of Mandera county”, Abdiasis Abu Musab, al Shabaab’s military operations spokesman, told Reuters on Wednesday.
The teachers were killed in a fire caused by the explosion in the attack at Arabia Boys Secondary School, police said on Twitter.
Police reservists guarding the school “engaged the attackers who then fled as more reinforcements were mobilised”, police said.
The al Qaeda-linked al Shabaab aims to topple Somalia’s U.N.-backed government and impose its own strict interpretation of Islam. They have intensified attacks in Kenya since it sent troops into Somalia in 2011.
