Hospital officials say a 16-year-old boy has died of gunshot wounds suffered when Islamic extremists attacked students at a northeast Nigerian school.

The death of Musa Mohammed on Wednesday raises the toll to 59 killed in Tuesday's attack.

Also Wednesday, a teacher said scores of students at an all-girl boarding school in Potiskum were sent home on orders of the Ministry of Education. Both schools are in Yobe state.

Girls were spared Tuesday but extremists have in the past abducted them as sex slaves.

Ten students suffering burns and gunfire and machete wounds still are in the hospital.

Tuesday's was the latest in a string of ever deadlier attacks in a 4-year-old Islamic uprising that has killed thousands despite a state of emergency and deployment of soldiers and jet bombers.
