ORLANDO, Fla. (AP) — A college student killed himself in a dorm at the University of Central Florida and authorities found explosives and guns in the room early Monday, authorities said, leading to the evacuation of hundreds of students and cancellation of morning classes.

University spokesman Grant Heston said normal campus operations resumed around noon after the makeshift devices were taken away from the dorm, which remained closed.

Authorities didn't immediately say what the student's intentions may have been.
