Sheriff’s officials say nobody was hurt when a federal officer fired a single shot while attempting to break up an altercation during a pro-Israel demonstration in Los Angeles.

The Los Angeles Times reports the Department of Homeland Security officer fired his weapon during the rally at the Federal Building in Westwood on Sunday.

Sheriff’s Deputy Juanita Navarro says the demonstration, which drew some 500 people, was breaking up when pro-Israel and pro-Palestinian supporters began to clash.

Navarro says the officer sought to intervene and fired his weapon once.

Authorities say pro-Palestinian protesters critical of Israel’s bombing of Gaza Strip settlements arrived at the rally, and some in the crowds began yelling at each other.

The Times says two people were arrested.

Sunday’s rally followed a similar one Saturday in support of Palestinians.
