"The curfew in the city of Atlanta has been extended starting tonight, 31 May 2020 at 9 pm and continuing through sunrise tomorrow 1 June 2020", the city authority tweeted.
Chicago Mayor Lori Lightfoot said that, in addition to indefinitely extending the curfew, she had asked Illinois Governor JB Pritzker to send in National Guard forces to help city police.
"In addition to our 9 pm-6 am curfew that will remain in place until further notice, Governor Pritzker — at my request — has ordered a small contingent of the National Guard to maintain a limited presence and support our police", she tweeted.
Multiple cities across the US saw the fifth night of protests on Saturday sparked by Floyd's death at the hands of a police officer in the city of Minneapolis. Thousands defied curfews, smashing windows, looting stores, and burning cars.
The National Guard has been activated in Minnesota, Georgia, Kentucky, Wisconsin, Colorado, Ohio, Tennessee, and Utah, and other US states.
