In Kenosha, Wisconsin, a gunman opened fire on a crowd of Black Lives Matter protesters late Tuesday, killing two people and injuring a third.

Protester 1: “Oh my god! Oh my god!”

Protester 2: “Medic! Medic! Medic! Medic!”

Video filmed by a bystander shows a young man with an assault rifle being followed by a crowd of protesters. He falls to the ground before shooting into the crowd as protesters attempt to disarm him. Kenosha police said early Wednesday morning that armed vigilantes had been in the streets, and they were looking for a man with a long gun. No arrests have been made yet, and those killed have not been identified.
