Rioting broke out between two rival groups of Eritreans in the Netherlands on Saturday night, police said. Officers used tear gas in an attempt to quell the unrest in The Hague as rioters torched police cars and a bus.

Images from the scene showed vehicles in flames and dozens of men in the street, some throwing rocks. “It got seriously out of hand,” The Hague Municipality spokesman Robin Middel said. He said a group loyal to Eritrea’s government was holding a meeting when the venue was attacked by Eritreans who oppose the African nation’s government.
