Missouri Gov. Jay Nixon has called for the Missouri National Guard to help quell the ongoing violence in Ferguson, Mo., following the death of unarmed teenager Michael Brown.
Sunday saw some of the most intense violence yet in the St. Louis suburb as the second night of a state-imposed curfew got underway. Protestors fired guns and firebombs at police and officers responded with tear gas and rubber bullets. Brown was shot to death Aug. 9 by a white police officer.
An autopsy Sunday showed Brown was shot six times.
