US National Guard began its withdrawal from Los Angeles, California, the KTLA channel reported.
The military guarded the city hall and helped the police control security in ongoing rallies.
The curfew was declared in LA from May 31 to June 4, but on Thursday, Mayor Eric Garcetti announced that he would not extend it.
As reported earlier, mass protests and riots broke out in many US states after the death of African-American George Floyd.
Three police officers handcuffed Floyd, threw him to the ground and apprehended him, and one of them pressed his knee on the man's neck. All four police officers involved in the detention have been fired and charged.
