At least 7 historically Black colleges receive bomb threats

• The threats, which prompted evacuations by students and faculty, have since been cleared and no bombs were found.

• It was not clear whether the threats were connected or if they were racially motivated, according to the Washington Post.

What they're saying: "While the full student body has not yet returned for the semester, students who are on campus have been relocated off-campus for the evening," the University of Arkansas at Pine Bluff said in a statement on Tuesday evening.

• "Although the threat was unfounded we ask that everyone remains vigilant."
