Incidents of arson, vandalism and clashes between police and protesters happened when demonstrations turned violent Sunday evening in Washington, D.C., with fire flaring up near the White House.

WASHINGTON, June 1 -- Washington, D.C. Mayor Muriel Bowser announced Monday that a curfew will be effective 7 p.m. Eastern Time in the city and extend through the next morning, and similar restrictions will also be issued for Tuesday.

The order came as protests over the death of George Floyd, a 46-year-old black man in Minneapolis, turned violent not only in the U.S. capital, but also cross the nation.

Bowser, who issued an 11 p.m. curfew Sunday night, said at a news briefing that journalists covering the demonstrations and other essential personnel are exempted from the new measure. "We want your voices to be heard, but we also want to protect the safety of everyone in our city."
