 A man reportedly entered the Jewish Museum in Brussels this afternoon and opened fire, killing at least three people.

The gunman arrived at the museum at around 15:50 (13:50 GMT) carrying a backpack, then opened fire before fleeing in a car, Belgian media reported.

Brussels Mayor Yvan Mayeur said three men and a woman had been caught up in the attack. "It's clearly extremely serious," RTBF quoted him as saying.

 While details are still emerging, the attack comes just weeks after a man in Kansas shot and killed three people at two different Jewish facilities outside of Kansas City.
