RALEIGH, N.C. (AP) — N.C. State University will test how it responds to an emergency by simulating an attack by a gunman on campus.

The exercise Friday mainly will focus on two dormitories. Students aren’t on campus because of the holiday break so the drill won’t interrupt their classes.

On Thursday, N.C. Central University in Durham held a similar exercise, one involving a terrorist attack. Students also weren’t on campus for that drill.

During the NCSU drill Friday afternoon, Harris parking will be closed. Vehicles also won’t be allowed to enter Cates Avenue between Dan Allen and Morrill drives. The school will allow outbound traffic there.
