The US state of Missouri where an unarmed black teenager was shot by the police, is sending in the National Guard to the town of Ferguson as protests continue.
Governor Jay Nixon signed an order to call in the army reservists to “help restore peace and order”.
Police managed to disperse angry crowds shortly before a second night under curfew began on Sunday.
The mother of Michael Brown has called for the arrest of the officer who killed her son on 9 August. He has been suspended pending a full investigation.
Officials last week confirmed that Darren Wilson, a six-year police veteran with no previous complaints against him, has been on paid administrative leave since the shooting.
In an interview with US media, Mr Brown’s mother said the only way to restore peace in Ferguson was by “arresting [Mr Wilson] and making him accountable for his actions”.
The tensions were fuelled by the release of a video allegedly showing the shot teenager robbing a store.
Missouri declared a state of emergency and imposed a curfew on Saturday in response to the escalating violence.
