A self-immolation outside the Israeli embassy in the capital leads to an investigation of the bomber, police said.

A man set himself on fire outside the Israeli embassy in Washington on Sunday afternoon and police examined a suspicious nearby vehicle for explosives, the Metropolitan Police Department in Washington said.

U.S. Secret Service officers extinguished the fire outside the embassy, ​​in northwest Washington, around 1 p.m., said Vito Maggiolo, a spokesman for the city’s fire department. The man was taken to a nearby hospital with life-threatening injuries and remains in critical condition.

The investigation continued and police had not cleared the accident scene as of Sunday afternoon. Secret Service agents and the Bureau of Alcohol, Tobacco, Firearms and Explosives worked with Washington’s explosive ordnance disposal unit to investigate the incident, said Sean Hickman, a police spokesman.

No embassy staff members were injured and all are missing, said Tal Naim, a spokeswoman for the Israeli embassy in Washington.

The Israeli embassy in Washington has been the scene of ongoing protests against the war in Gaza, as civilian casualties continue to rise in the devastated enclave, with more than 29,000 dead, local health ministry officials said.

In December, a protester set himself on fire in front of the Israeli consulate in Atlanta, in what police said was “likely an extreme act of political protest.”
