The death toll has risen to 49 after a suicide bomber disguised in a school uniform blew himself up at a boys' secondary school in northern Nigeria on Monday, national television reported.
The report said 57 people were injured. Other reports put the number of injured victims at 79 in the attack in Potiskum, Yobe state, which took place as students were in the yard of the boarding school during the morning roll call.
Police Commissioner Markus Danladi said the exact number of casualties could not be confirmed until he had reached the site, which is about 120km from the state capital, Damaturu.
