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 armored vehicles to push demonstrators back. Officers also fired tear gas and flash grenades.

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 as well.

At least three journalists were arrested and detained before being released — a photographer for Getty and two German reporters. There were no reports of serious injuries.
