The airman, who filmed the incident and could be heard yelling “Free Palestine,” was hospitalized with life-threatening injuries after collapsing to the ground.

The U.S. Air Force member who set himself on fire outside the Israeli Embassy in Washington, D.C., in an apparent protest against the Israel-Hamas war has died, according to a U.S. official.

Next of kin notification is continuing, so the Air Force won’t release his name until 24 hours after the final notification is complete.

The District of Columbia Fire and Emergency Medical Service Department responded to a call about a person on fire outside the embassy just before 1 p.m. Sunday, and found the flames extinguished by the Secret Service’s uniformed division.
