In the statement, which blamed "many from outside the community and state" for "putting the residents and businesses of Ferguson at risk," Nixon condemned "violent criminal acts" such as "firing upon law enforcement officers, shooting a civilian, throwing Molotov cocktails, looting, and a coordinated attempt to block roads and overrun the Unified Command Center."

Authorities have imposed a curfew for a second night in Ferguson, Missouri, in an attempt to calm the unrest following the Aug. 9 shooting death of Michael Brown, an unarmed black teen, by a local police officer. Over the past few days, Brown's shooting death has sparked riots, looting and clashes between police and protesters, and triggered a federal investigation.

Amnesty International, which has called for an investigation into tactics used by police at the site of the protests, is reportedly sending its team to Ferguson, making it the first time that the London-based human rights organization will dispatch a team to the U.S. A SWAT team has also reportedly responded to clashes on the street where Brown was shot. And, more journalists were reportedly arrested and released Sunday night.

On Sunday, a preliminary autopsy conducted by Dr. Michael Baden, a former New York City chief medical examiner, revealed that Brown had been shot six times, and that one of the bullets entered his skull and caused a fatal injury, The New York Times reported. The autopsy, which was performed at the request of Brown’s family, also showed that four shots were fired in his right arm and that the shots did not appear to have been fired from a close range. The officer who shot Brown has been identified as Darren Wilson.

According to media reports, officials reported that a grocery store caught fire amid clashes between protesters and police, while there were also reports of looting on Sunday. According to USA Today, seven people were arrested and one person was shot early Sunday as police fired tear gas to control the crowds. 

A Ferguson journalist Robert Klemko tweeted saying that he was arrested for two minutes, even though reporters on the site followed the instructions of local authorities.
