MINNEAPOLIS (AP) — Muslim leaders in the Twin Cities are urging police and the FBI to investigate weekend vandalism at a Minneapolis mosque as a hate crime.

Minnesota Public Radio News reports surveillance video from the Salaam Cultural Center shows a person throwing rocks through a glass entry door and then kicking out the remaining broken glass early Sunday morning.

Minneapolis police are investigating the vandalism. But, police spokesman John Elder says the vandal did not leave any indication of motive, such as graffiti, so it would be hard to prove racial or religious bias.

The Minnesota director of the Council on American Islamic Relations, Jaylani Hussein, says mosques have been on edge since the attacks in Christchurch, New Zealand in March and the 2017 firebombing of the Dar Al Farooq Islamic Center in Bloomington.
