LUVERNE, Ala. — An Alabama school district has canceled classes for Tuesday after receiving information about a threat.

News outlets report that Crenshaw County Schools said in a statement that authorities informed them about a potential threat Monday. The threat wasn’t directed at a specific school. WSFA-TV reports that Crenshaw Christian Academy and Luverne Head Start have also closed for Tuesday.
