FARGO, N.D. (AP) - North Dakota State University officials are ordering the campus evacuated after receiving a bomb threat.

NDSU issued a statement shortly before 10 a.m. Friday telling all employees and students to leave campus within a half-hour because of a bomb threat. Students in residence halls have been told to walk to locations off campus. No other details were given.

The University of Texas at Austin also has ordered an evacuation after receiving a bomb threat. It is not known if the two threats are related.

More than 14,000 students are enrolled at NDSU.

The University of Texas has also evacuated all campus building after receiving phoned-in threat that multiple bombs had been placed on campus. Officials say no bombs have been found.

An alert posted shortly before 10 a.m. Friday says people on campus should immediately evacuate all buildings and "get as far away as possible."

University of Texas director of communications Rhonda Weldon says the university received a call about 8:35 a.m. from a man claiming to be with al-Qaida. The man said he'd placed bombs all over the campus that would go off in 90 minutes.

Wheldon says all buildings were evacuated at 9:50 a.m. as a precaution.

It was unclear whether the two evacuations were related.
