In photos: Protesters and police clash nationwide over George Floyd

Police used tear gas, rubber bullets and pepper spray as the protests sparked by the killing of George Floyd continued nationwide into early Sunday.

The big picture: Police responded over the weekend with force, in cities ranging from Salt Lake City to Atlanta to Des Moines, Houston to Detroit, Milwaukee to Washington, D.C., Denver and Louisville. Large crowds gathered in Minneapolis on Saturday for the fifth day in a row.

• Multiple cities imposed curfews for Saturday night as police continue to try to break up crowds.
• Civil rights icon Rep. John Lewis (D-Ga.) was among the leaders to urge protesters to demonstrate peacefully amid reports of looting and the burning of buildings in some places. "Be constructive, not destructive," Lewis said.

City is shutting it down, enforcing curfew. People moved out of area. Streets are clearing out. I saw at least a half dozen people get arrested. Many looters have left the area, but there are stragglers. @KYWNewsradio #riots2020 #georgefloyd #phillyprotest pic.twitter.com/5pB3xOMtLF

What's happening: Demonstrators are demanding justice for the killing of Floyd, a black man who died Monday after at least one police officer pinned him to the ground with a knee to his neck.

• The officer involved in Floyd's death was charged with third-degree murder on Friday, after protests had continued in Minneapolis for three days.
