A trio of universities were disrupted by violent threats this morning although all three campuses were later determined to be safe, according to the schools, according to ABC News.

University of Texas president William Powers, Jr., said today that the school was "extremely confident" that the campus was safe and free of explosive devices as of 1 p.m., following a bomb threat placed to the school around 8:30 a.m. this morning.

Shortly after the University of Texas announced its bomb threat, North Dakota State University in Fargo, N.D., announced that it too had been the target of a bomb threat and was evacuating students.

A third university, Valparaiso University in Indiana, announced that it had received a violent threat as well in the form of a graffiti message.

All three campuses have since been cleared. Officials said they do not yet know if the threats are related.
