While today marks the end of the Mayan calendar, not the end of the world, some schools are taking extra security precautions and one North Dakota school district scrapped classes all together reports the Grand Forks Herald.

Minot Public Schools cancelled classes Friday because of growing rumors about the Mayan calendar’s supposed prediction that the world will end and concerns for student safety.

It’s only one of several school districts in North Dakota and Minnesota grappling with rumors of school violence that have combined with heightened fears in the wake of a shooting last week that took the life of 26 students and teachers at a Newtown, Conn., school.

At Moorhead High School, a threatening rumor prompted extra security Thursday. Police said they looked into the rumor on Wednesday and found it to be false, but added an extra officer for peace of mind.

At Bemidji High School, police spent Thursday trying to get to the bottom of a threatening rumor, found it baseless, but added security just in case.
