Two militants have attacked a business college in Potiskum in the north-eastern Nigerian state of Yobe, the BBC reported Friday.

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 .
