Minneapolis police are searching for "three white male suspects" who opened fire at a Black Lives Matter protest late Monday night, shooting and wounding five people.

Deputy Police Chief Medaria Arradondo said the victims were taken to the North Memorial Medical Center and Hennepin County Medical Center (HCMC) where they are being treated for non-life-threatening injuries, reports the Star Tribune. Meanwhile, a person at the scene said one of the victims had been shot in the stomach, and was undergoing surgery overnight at HCMC.

The shooting occurred as demonstrators were protesting the recent police shooting of Jamar Clark at the Fourth Precinct Monday night. That's when "white supremacists" showed up to the rally "in an act of domestic terrorism," said the local Black Lives Matter group a Facebook post, according to Newsweek.

A woman named Jie Wronski-Riley said at least two of the three men were antagonizing the peaceful protesters, while Miski Noor, a media contact for Black Lives Matter, said "a group of white supremacists showed up at the protest, as they have done most nights." Dana Jaehnert added that one of the three counterdemonstrators was wearing a mask.

About a dozen protesters attempted to herd the group away from the area, said Noor, and the gunman "opened fire on about six protesters," hitting five of them at 10:45 p.m. about a block away from the precinct station. The attackers then fled the scene.

Following the shooting, Nekima Levy-Pounds, president of the Minneapolis chapter of the NAACP, released a statement saying she was "appalled that white supremacists would open fire on nonviolent, peaceful protesters."

Eddie Sutton, Clark's brother, also issued this statement early Tuesday morning in response to the shootings, saying, "Thank you to the community for the incredible support you have shown for our family in this difficult time. We appreciate Black Lives Matter for holding it down and keeping the protests peaceful. But in light of tonight's shootings, the family feels out of imminent concern for the safety of the occupiers, we must get the occupation of the 4th precinct ended and onto the next step."

Protesters have been demonstrating at the Fourth Precinct even since Clark, a 24-year-old unarmed black man, was fatally shot by two Minneapolis police on Sunday, Nov. 15.

According to the Minnesota Department of Public Safety's Bureau of Criminal Apprehension, Clark was a suspect in a domestic violence case and he interfered when first responders arrived on the scene to help a woman who said she has been assaulted, reports The Atlantic.

"The two Minneapolis police officers responded to a request for assistance from paramedics who reported an individual, now identified as Mr. Clark, disrupting their ability to aid an assault victim at that location," reads the statement.

"Minneapolis police have said that Mr. Clark was a suspect in the assault. At some point during an altercation that ensued between the officers and Mr. Clark, an officer discharged his weapon, striking Mr. Clark," state authorities said.

However, several eye witnesses say Clark was handcuffed and lying flat on his stomach when he was shot in the head, although police insist he was not.

"The young man was just lying there; he was not resisting arrest," said Teto Wilson, according to the local NAACP chapter. "Two officers were surrounding the victim on the ground, an officer maneuvered his body around to shield Jamar's body, and I heard the shot go off."
