Teen Shooting Unrest: National Guard Called In
Missouri Governor Jay Nixon has ordered the National Guard to Ferguson amid rising tensions over the shooting death by police of an unarmed black teenager.
Mr Nixon said the National Guard would "help restore peace and order" to the St Louis town after days of protests over the death of 18-year-old Michael Brown.
In the latest violence on Sunday night, police fired tear gas at demonstrators as gunfire was heard.
The announcement by Mr Nixon came as a preliminary private autopsy found that Mr Brown was shot at least six times including twice in the head, according to the New York Times.
The post-mortem examination was carried out by Michael Baden, a former New York City chief medical examiner, at the request of Mr Brown's family.
Dr Baden said one of the bullets entered the top of Mr Brown's skull, suggesting that his head was bent forward when he suffered a fatal injury.
Mr Brown was shot four times in the right arm and all the bullets were fired into his front, he told the New York Times.
Attorney General Eric Holder has ordered a federal medical examiner to perform another autopsy.
As night fell in Ferguson, a peaceful protest quickly deteriorated into further violence - more than a week after Mr Brown's killing on August 9.
Some protesters carried signs protesting against police brutality. Some had their hands up in the air, while others threw Molotov cocktails at police officers.
Authorities said they were responding to reports of gunfire, looting and vandalism.
The Missouri Highway Patrol also said it used tear gas to disperse "aggressors" who were trying to infiltrate a law enforcement command post, and that armoured vehicles were deployed to ensure public safety.
Captain Ron Johnson said there were "acts of violence that appear to not have been spontaneous, but premeditated attacks designed to damage property, hurt people, and provoke a response".
A man was shot and critically wounded in the area, but not by police, and someone also shot at a police car, authorities said.
Seven people were arrested for failing to disperse.
Officials announced another five-hour curfew for the second night running which started at midnight local time (6am UK time). But much of the violence started before the curfew.
Authorities said they plan to decide on a day-by-day basis whether to extend the curfew, first imposed on Saturday night by Mr Nixon in an effort to quell the demonstrations.
Mr Nixon meanwhile sharply criticised the town's police for releasing CCTV video which they say shows Mr Brown stealing cigars from a store and shoving an employee.
"I think it had an incendiary effect," he told CBS' Face The Nation on Sunday morning.
He said police "clearly are attempting to besmirch a victim of a shooting".
Minutes after the alleged robbery, Mr Brown had the encounter with an officer who police say stopped the teenager for jaywalking.
Mr Brown was unarmed and it has been claimed he was trying to surrender before he was shot dead by white police officer Darren Wilson, 28.
