LOS ANGELES (November 19, 2012)--Los Angeles police formed skirmish lines during a street clash between Palestinian supporters and a pro-Israel group staging a rally, but nobody was arrested.

KNX radio reports one man broke his arm during a fight with a demonstrator during the Sunday afternoon event outside the Westwood federal building.

The rally attracted more than 1,000 pro-Israel supporters amid renewed fighting in the Gaza Strip, where Israel is retaliating for Hamas rocket attacks.

After the event began, a group of about 250 Palestinian supporters began demonstrating on the opposite side of Wilshire Boulevard.

That triggered a Los Angeles Police Department tactical alert that drew police officers, sheriff's deputies and the California Highway Patrol officers who formed skirmish lines until the demonstrators eventually left.
