Anti-lockdown protests turned violent in Dutch cities after the country introduced an overnight curfew on Saturday, its toughest lockdown since the start of the COVID-19 pandemic. The third night of unrest led to 151 arrests, extra riot police, looting and fireworks. Prime Minister Mark Rutte said on Monday: "This has nothing to do with protesting. This is criminal violence." Dutch police said the riots on Sunday were the worst the country had seen in four decades.
