Update: Atlanta mayor extends curfew to Sunday

Atlanta Mayor Keisha Lance Bottoms announced a 9 p.m. curfew Saturday night, the day after demonstrations in the city turned violent.

The curfew extends until sunrise Sunday.

Bottoms' executive order comes "as a result of the recent acts of violence demonstrated throughout the city," according to a tweet from the city of Atlanta.

Protests that began downtown Friday afternoon spread to Buckhead late Friday night and into Saturday morning as participants broke windows, set fire to vehicles and looted stores. The city is preparing for a repeat of the incidents Saturday.
