WASHINGTON — An active-duty member of the U.S. Air Force was critically injured Sunday after setting himself ablaze outside the Israeli Embassy in Washington, D.C., while declaring that he “will no longer be complicit in genocide,” a person familiar with the matter told The Associated Press.

Police said they responded to the scene around 1 p.m. "to assist the United States Secret Service after an individual set themselves on fire." Einav Hadari, a spokesperson for the Israeli embassy, confirmed the incident and said the man's identity was not known to them. No embassy staff were injured, he added.

The man was livestreaming on the video streaming platform Twitch, the person told The Associated Press. Law enforcement officials believe the man started a livestream, set his phone down and then doused himself in accelerant and ignited the flames. At one point, he said he “will no longer be complicit in genocide,” the person said. The video was later removed from the platform, but law enforcement officials have obtained and reviewed a copy.

Uniformed Secret Service agents extinguished the fire and the man was transported to a nearby hospital "with critical, life-threatening injuries," D.C. Fire and EMS Department spokesperson Vito Maggiolo said.

An MPD explosives disposal team was dispatched to the scene "in reference to a suspicious vehicle that may be connected to the individual," a police spokesperson wrote in an email. As of 3 p.m. ET, it remained an active investigation.

Police did not immediately provide any additional details about the incident.

The incident happened as Israeli Prime Minister Benjamin Netanyahu is seeking the cabinet approval for a military operation in the southern Gazan city of Rafah while a temporary cease-fire deal is being negotiated. Israel’s military offensive in Gaza, however, has drawn criticisms, including genocide claims against the Palestinians.

Israel has adamantly denied the genocide allegations and says it is carrying out operations in accordance with international law in the Israel-Hamas war.
