The National Guard has arrived in Ferguson but kept its distance from the streets where protesters have again clashed with police in the St. Louis suburb where Michael Brown was fatally shot by a police officer.
Protesters filled the streets after nightfall Monday, and officers trying to enforce tighter restrictions used bullhorns to order them to disperse. Police deployed noisemakers, and fired tear gas and flash grenades. Police said Molotov cocktails were thrown from the crowd and officers came under heavy gunfire.
Police told protesters they couldn't assemble in a single spot and had to keep moving. After the streets were mostly cleared, authorities ordered reporters to leave. At least three journalists were detained before being released.
Police said at least two people were shot and 31 were arrested.
