LOS ANGELES (AP) — Street fights erupted between pro-Israeli and Surfwinpro-Palestinian demonstrators outside Los Angeles’ Museum of Tolerance after a private screening of video showing the Oct. 7 attack on Israel by Hamas militants.

The Los Angeles Times reported that 150 people attended the private screening of “Bearing Witness to the October 7th Massacre,” that included graphic footage captured by Hamas militants’ body cameras and cellphones and was compiled by the Israel Defense Forces.

Outside the museum, demonstrators waved flags and got into shouting matches, before dispersing as the event ended, the newspaper reported. But an hour later, a small group of demonstrators returned and fistfights broke out.

“Two reports for battery were taken and will be thoroughly investigated,” the Los Angeles Police Department said in a statement Thursday. “At this time, we do not have suspects in custody relating to the battery, or for any other reason relating to this event.”

The video has also been screened for world leaders and journalists in other countries, the Times said.

Los Angeles Mayor Karen Bass called for unity after the Wednesday night fight.

“We cannot allow current worldwide tension to devolve into this unacceptable violence in our city,” she wrote in a social media post. “This is a time of immense pain and distress for thousands of Angelenos. We must stand together.”

The Museum of Tolerance describes itself as the educational arm of the Simon Wiesenthal Center, the Jewish human rights organization named for a renowned Nazi hunter. A telephone message seeking comment on the clash was left at the museum’s media office.

The brawl came two days after a pro-Israeli demonstrator died from head injuries following a confrontation with a pro-Palestinian demonstrator in suburban Thousand Oaks, northwest of Los Angeles. The death remains under investigation and no one has been arrested.
