Following some of the pro-Israel supporters being allegedly hit with sticks, Kaple said “a melee ensued.”

The men reportedly jumped back into their truck and took off.

At this point, officers with Homeland Security approached the men.

A witness told Kaple one of the Homeland Security officers fired at the truck. No one was struck. At least one person was arrested.

“I saw my flag on the ground,” Hany Reai, a Palestinian supporter, said “and I saw a man step on it. I’m not here to fight. I just need my flag and I ran to take it.”
