*Authorities on Monday lifted the overnight curfew for Ferguson, Missouri, after two nights.

The announcement came from Gov. Jay Nixon, who earlier in the day ordered the National Guard to the St. Louis suburb after a week of clashes between police and protesters over the police shooting death of an unarmed black teenager.

Nixon said that the National Guard would have a limited mission and that overall command would still be the responsibility of the Highway Patrol, which took over security in Ferguson on Thursday.

The National Guard, under the command of Brig. Gen. Gregory Mason, will “provide protection, and ensure the safety of our Unified Command Center, which was the target last night of a coordinated attack,” Nixon said.

Nixon said that law enforcement officers were the target of gunfire on Sunday. The violence also included firebombs, looting and “a coordinated attempt to overrun the unified Command Center,” Nixon said.

The curfew was in place midnight to 5 a.m. Sunday and Monday.
