Belgian police detained dozens of people on Sunday after Morocco’s 2-0 World Cup win over Belgium at the World Cup which triggered riots in Brussels.

Brussels police said in a statement: “At around 3:22 pm, dozens of masked persons sought a confrontation with the security services, jeopardizing public safety.”

Several riots took place across the Belgian capital where dozens of soccer fans, some draped in Moroccan flags, clashed with riot police, setting a car on fire as well as electric scooters.

“It was immediately decided to proceed to a police intervention, with the use of a water cannon and tear gas,” the Brussels police said.

The statement concluded “Calm returned around 7 p.m. and preventive patrols are still present in the sectors concerned.”

The victory against Belgium was Morocco’s first win at a World Cup since 1998 and it is their third ever.

Abdelhamid Sabiri scored with a free kick in the second half before Zakaria Aboukhlal sealed the famous win with Morocco’s second goal in stoppage time.
