Police fired tear gas Monday in another night of unrest in a Missouri town where a caucasian police officer shot and killed an unarmed African-Amarican teenager, just hours after President Barack Obama called for calm.
US National Guard troops rolled into Ferguson earlier in the day, but they kept a low profile as police in riot gear dispersed about 100 demonstrators around 11 p.m. (0400 GMT), arresting several of them.
Several rounds of gunfire — described by a senior police officer as “potshots in the area” — were heard, adding to tension that has gripped this St Louis suburb since the fatal shooting of 18-year-old student Michael Brown.
His death, and the heavy-handed police response, has reignited a national debate about race and law enforcement in the United States.
