At least five officers were injured as fresh clashes erupted in Minnesota while the people took to the streets in another night of protests against the shootings of two black men in Louisiana and Minnesota.
Scuffle broke out overnight on Saturday in St. Paul, Minnesota, where the protesters clashed with police on Interstate 94, reports CNN.
The authorities said that the demonstrators blocked the freeway and threw bottles, bricks and fireworks at the police personnel, thereby injuring at least five officers.
One policeman was hit with a glass bottle and another by fireworks, according to St. Paul police.
Another was hit on the head with a large piece of concrete and one more was hit on the head with a rock.
Police spokesman Steve Linders said the police used crowd control measures, including smoke, and fired marking rounds similar to paintball rounds.
By morning, the police arrested 50 people.
The unrest took place just miles from where Philando Castile, one of the victims, was shot by the police.
As many as 200 people forced their way past Minnesota state patrol troopers, who were trying to block them from getting on the road.
After hours of clashes, things appeared calmer and a cleanup ensued.
More protests unfolded in cities including Washington, D.C., Atlanta, Miami and Fort Lauderdale, Florida, to decry police brutality after last week's killing of Sterling and Castile.
