(BBC) – Two militants have attacked a business college in Potiskum in the north-eastern Nigerian state of Yobe.
At least six students were seriously injured by gunfire, but dozens more were hurt as they tried to escape.
The gunman was accompanied by a suicide bomber, who blew himself up in the car park.
No-one so far has said they were behind the attack but the Islamist militant group Boko Haram has carried out similar raids in the town .
The name Boko Haram, loosely translated from the region’s Hausa language, means “Western education is forbidden”.
