Gunmen killed 29 students and one teach in an attack on a boarding school in Nigeria's northeast,

Survivors being treated for burn and gunshots wounds said some students were burned alive in the attack on the Government Secondary School in Mamudo town in Yobe state early on Saturday.

As he wept over the bodies of his two boys, farmer Malam Abdullahi swore he would withdraw three remaining sons from a nearby school.

He complained there was no protection for students despite the deployment of thousands of troops since the government declared a state of emergency mid-May in three northeastern states.

Dozens of schools have been torched and unknown scores of students killed among more than 1,600 victims slain by armed groups since 2010
