Nigerian Islamists ? 59 pupils in boarding school attack

DAMATURU, Nigeria, Feb 25 (Reuters) - Gunmen from Islamist group Boko Haram shot or burned to death 59 pupils in a boarding school in northeast Nigeria overnight, a hospital official and security forces said on Tuesday.

"Some of the students' bodies were burned to ashes," Police Commissioner Sanusi Rufai said of the attack on the Federal Government college of Buni Yadi, a secondary school in Yobe state, near the state's capital city of Damaturu.

Bala Ajiya, an official at the Specialist Hospital Damaturu, told Reuters by phone the death toll had risen to 59.

"Fresh bodies have been brought in. More bodies were discovered in the bush after the students who had escaped with bullet wounds died from their injuries," he said.

Rafai, who had given an earlier estimate of 29 killed, said all those killed were boys. He said the school's 24 buildings, including staff quarters, were completely burned to the ground.

The Islamists, whose struggle for an Islamic state in northern Nigeria has killed thousands and made them the biggest threat to security in Africa's top oil producer, are increasingly preying on the civilian population.

Militants from Boko Haram, whose name means "Western education is sinful" in the northern Hausa language, have frequently attacked schools in the past. A similar attack in June in the nearby village of Mamudo left 22 students dead.

They have killed more than 300 people this month, mostly civilians, including in two attacks last week that killed around 100 each, one in which militants razed a whole village and shot panicked residents as they tried to flee.

That attack prompted U.S. Secretary of State John Kerry to condemn Boko Haram for "unspeakable ... acts of terror".
