Mayor Karen Bass reduced the hours that a nightly curfew in downtown Los Angeles is in effect on Monday, allowing struggling businesses to remain open later into the evening.

The mayor said the curfew will run from 8 p.m. to 6 a.m. local time, and cover roughly a square mile of downtown. She said she expects it to last several days.

Downtown Los Angeles fell silent Tuesday night as a mandatory curfew took effect, marking a turn in the city’s response to five consecutive days of escalating unrest.
