A man shot off his gun at dueling Israel-Palestine protests in Illinois Sunday, the same day a driver drove into a crowd of Palestine supporters in Minnesota as tense demonstrations over the Israel-Palestine conflict gripped parts of the country Sunday.

While nearly 20 New York City demonstrators were arrested during an anti-Israel protest Saturday in Brooklyn, rallies in Illinois, Minnesota and Oregon were marred with violent outbursts over the weekend, according to authorities in those states.

During a pro-Israel event in Skokie, Illinois, about 200 pro-Palestinian protesters showed up to demonstrate, Lincolnwood police said. Outside the event across the street, a man was confronted by a number of people in a town center mall when he pulled out a firearm and shot it into the air Sunday afternoon, Lincolnwood police said in a press release.

The man was quickly arrested and no one was injured.

At the same protest, a person was hit by a vehicle in a hit-and-run in a separate incident, though the victim only required treatment at the scene, according to Lincolnwood police.
