Protesters marched again Saturday in cities nationwide to decry police brutality after the killing of two African-American men by police this week.
While many were peaceful, events turned ugly in St. Paul, Minnesota, where protesters clashed with police on Interstate 94.
At least two officers were injured by protesters — one hit with a glass bottle and the other by fireworks, according to St. Paul police.
Police used crowd control measures including smoke, police spokesman Steve Linders said.
Parts of the freeway are closed after as many as 200 people forced their way past Minnesota state patrol troopers who were trying to block them from getting on the road.
