A college attacked by Boko Haram in northeast Nigeria says one of five students wounded by gunfire has died.

A notice posted at the College of Business and Administrative Studies in Potiskum town says Musa Umar Gamari died on Monday.

A suicide bomber and a gunman attacked the school on Saturday with gunfire and two explosions before they were overcome by police and soldiers.

Another 45 people injured themselves by jumping out of windows and scaling walls to escape.

It was the first school attack reported since a 3-month-old multinational offensive drove the Islamic extremists out of towns seized last year. Nigeria's military says the main fighting force is hemmed into the Sambisa Forest where they are being pursued.

The nickname Boko Haram means "Western education is sinful."
