Officers deployed tear gas and a water cannon after demonstrators hurled rocks and bottles, and a police car was set on fire
Dutch police used tear gas and a water cannon to disperse violent anti-migration protesters in The Hague on Saturday, local authorities said.
Thirty people have been arrested, and two police officers were injured. Authorities did not rule out additional arrests in the coming days as they review camera footage.
Thousands of people had joined a protest organised by a right-wing activist, demanding stricter migration policies and a clampdown on asylum seekers, just over a month before a national election.
Large groups of protesters, many waving Dutch flags and flags associated with far-right groups, clashed violently with the police, throwing rocks and bottles, footage from broadcaster NOS showed.
