A protester who works in the media lit himself on fire outside of the White House during an anti-Israel protest on Saturday evening, disturbing video shows.

The man, identified as photojournalist Samuel Mena Jr, can be seen screaming in pain after he set his left arm ablaze in the middle of the street as shocked police officers and bystanders rush over to help.

Mena holds his left arm — engulfed in flames — high in the air to show others as several people quickly douse him with water and beat out the flames with pieces of clothing.

He cries out that he is a journalist as he’s restrained by DC Metropolitan police officers, according to another clip after the fire had been extinguished.

The left sleeve of his burnt shirt appears drenched in liquid and pink, superficial burns can be seen on his bare arm.

One passerby pours his bottle of water on the wound, video shows.

“We spread the misinformation,” Mena screams at one point in the video as a crowd gathers around him.

“I’m a journalist and I said it was okay,” he yells as a woman embraces him.

A white-shirt officer jumps into the scene and screams at onlookers to “back it up,” pushing some out of the way, the video shows before cutting out.

In a lengthy blog posted to his website before the incident on Saturday, Mena questioned the media’s objectivity in its coverage of the war in Gaza.

“To the 10 thousand children in Gaza that have lost a limb in this conflict, I give my left arm to you,” he wrote. “I pray my voice was able to raise up yours, and that your smiles never disappear.”

The journalist, a graduate of Arizona State University’s Walter Cronkite School of Journalism, had spent the last two years working for local CBS affiliate AZFamily, according to his LinkedIn profile.

Mena lit himself on fire in the 800 block of 16th Street just outside of the White House around 5:45 p.m., according to the Washington DC Metropolitan Police.

DC Fire and EMS responded and transported the man to an area hospital with non-life threatening injuries, cops said.
