Joseph Neumeyer, who is also a German citizen, approached the building on May 19 with Molotov cocktails, officials say.
A dual United States and German citizen has been arrested on charges that he travelled to Israel and attempted to firebomb the branch office of the US Embassy in Tel Aviv, federal prosecutors in New York have said.
Israeli officials deported Joseph Neumeyer to New York on Saturday and he had an initial court appearance before a federal judge in Brooklyn on Sunday. His criminal complaint was unsealed on Sunday.
Prosecutors say Neumeyer walked up to the embassy building on May 19 with a backpack containing Molotov cocktails, but got into a confrontation with a guard and eventually ran away, dropping his backpack as the guard tried to detain him.
Law enforcement then tracked Neumeyer down to a hotel a few blocks away from the embassy and arrested him, according to a criminal complaint filed in the Eastern District of New York.
“This defendant is charged with planning a devastating attack targeting our embassy in Israel, threatening death to Americans, and [US] President [Donald] Trump’s life,” US Attorney General Pam Bondi said in a statement. “The Department will not tolerate such violence and will prosecute this defendant to the fullest extent of the law.”
Neumeyer’s court-appointed attorney, Jeff Dahlberg, declined to comment.
The attack took place against the backdrop of Israel’s ongoing deadly war on Gaza, now in its 19th month. Nearly 54,000 Palestinians have been killed in the blockaded enclave, where a famine is now looming as Israeli forces continue to seal vital border crossings and uphold a crippling blockade on humanitarian aid including food, medicine, and fuel.
Neumeyer, 28, who is originally from Colorado and has dual US and German citizenship, had travelled from the US to Canada in early February and then arrived in Israel in late April, according to court records.
He had made a series of threatening social media posts before attempting the attack, prosecutors said.
During his first term, Trump recognised Jerusalem as Israel’s capital despite Palestinian objections, in a move that has not been recognised by the international community. He also moved the US Embassy to Jerusalem from Tel Aviv.
