Violent clashes broke out between hundreds of protesters and police at the Occupy Oakland demonstration in California late Tuesday.

Police fired tear gas and used bean bag rounds to disperse demonstrators, the Los Angeles Times reports. By the end of the night, police had arrested more than 100 demonstrators, it reports.

This video from ABC News shows chaotic scenes of people running in fogs of gas as loud explosions -- reportedly the firing of stun grenades -- can be heard.

"On the street it had the look and feel of a warzone," the ABC News correspondent says.

The clashes with police happened after the protesters marched to City Hall in an attempt to reclaim their camp. Protesters had been evicted from the camp earlier in the day.

Police reportedly told the protesters to leave and fired the tear gas after their orders were not followed.

"We were in a position where we had to deploy gas in order to stop the crowd and people from pelting us with bottles and rocks," Oakland's interim police chief, Howard Jordan, told the Los Angeles Times.

Earlier Tuesday, about 200 police, many in riot gear, made an attempt to completely shut down the Occupy Oakland protest.

Police from 10 different agencies raided the encampment outside of Oakland's City Hall before dawn, clearing the square of its approximately 150 tents in under 30 minutes, and reportedly arresting dozens of protesters.

The San Francisco Chronicle looks at the police plan to break up the camp.
