Northern Ireland's top police officer on Saturday condemned violent clashes that left 56 of his officers injured as "mindless anarchy"—and warned that many arrests will follow.
The disorder broke out in central Belfast as loyalists held counter-protests Friday evening against a nationalist march.
The Police Service of Northern Ireland said Friday that 26 officers had been injured, with five of them needing hospital treatment. But that tally more than doubled on Saturday.
Seven arrests have been made so far, police said.
Warning of more to come, Chief Constable Matt Baggott said, "Significant custodial sentences will be handed down in the weeks and months that follow—the prisons will be bulging, sadly."
