Double bomb attack hits school in north Cameroon: Official

A suspected double suicide bomb attack hit a school in north Cameroon on Thursday, a local official said, the latest attack in the central African country which is struggling to contain violence blamed on Boko Haram militants based in neighbouring Nigeria.

"The double attack occurred in the public school in the town of Kerawa," the official said. "We have no more information on the situation." A second source also confirmed the attack. The number of dead or wounded was not immediately known.

While there was no immediate claim of responsibility for the attack, northern Cameroon has become the scene of increasingly frequent suicide attacks as Boko Haram Islamist militants step up cross-border attacks that have also hit Chad and Niger.

One source said the school in Kerawa had been housing Nigerian refugees. Boko Haram has killed thousands of people and driven more than two million people from their homes during its six-year insurgency in one of the world's poorest regions.
