“Black Lives Matters” Protesters Back On U.S Streets

Protesters included a mixed-race couple carrying a sign that said, "Injustice anywhere threatens justice everywhere," and a little girl with her parents, wearing a white tank-top with the words "My life matters" written on it in marker.

Eugene Puryear, the march organizer, said the shooting of five police officers in Dallas on Thursday was tragic but inevitable because of police violence against African-Americans.

"We're at a tipping point," he said.

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.

In Washington, a group marched peacefully through downtown Saturday night, chanting, "We young. We strong. We marching all night on." They temporarily shut down Rock Creek Parkway.

About 400 people covered a city block as marchers moved across a large area of northwest Washington and headed toward the Georgetown neighbourhood late in the night.

It was the third night of marches in Washington.
