A man was arrested on Sunday at John Kennedy Airport in New York The U.S. embassy in Tel Aviv said in a statement.

The man named Joseph Neumeyer, a dual American and German citizen, was detained in Israel on May 19 after a hostile confrontation The Justice Department said security guards were in front of the office earlier that day.

The statement said the guard tried not to detain Nomiye, who abandoned the backpack he carried to release.

The statement added that the confrontation “revealed three basic improvisation burner devices,” and he searched the backpack left by the embassy. Officials were able to track Neumeyer to his hotel, where he was arrested.

The Justice Department also said that Neumeyer, 28, posted the following on social media: “Join me when I burned down the Tel Aviv embassy.

He also made threats on social media to assassinate President Donald Trump, the statement added.

It is not clear whether Neumeyer retained the attorney. Representatives of the New York Federal Defenders did not immediately respond to a request for comment Sunday night.

Neumeyer claimed in a NBC News-verified social media profile that he is the founder and CEO of a company called Atlas Light Co. It is unclear what the company has done, and Neumeyer claims to have built many startups.

Recent Facebook posts on Facebook have been dissatisfied with the West, especially with the United States and Trump.

The Justice Department said Neumeyer arrived in Israel last month but did not go to the U.S. Embassy in Tel Aviv until May 19. It is unclear where he was or what he did there before last week.

The White House did not immediately respond to a request for comment.

"The department will not tolerate such violence and prosecute the defendant to the maximum extent," U.S. Attorney General Pam Bondi said in a statement after Israel handed over Neumeyer to the United States on Sunday.

"This mean and violent behavior will be intolerable at home or abroad, and the FBI works with our partners to bring him to face justice for dangerous actions," FBI Director Kash Patel added in a statement.

Neumeyer, deported to the United States by Israeli authorities, could face up to 20 years in prison if convicted.

Two staff members working at the Israeli embassy in Washington were killed for several days during an event held in the capital Jewish Museum.

The suspect in the shooting was later charged with two counts of first-degree murder. According to the video taken on the scene and posted on social media, Rodriguez was arrested and shouted "Free, Free Palestine".

Trump and Israeli Prime Minister Benjamin Netanyahu spoke the day after the shooting, which Netanyahu condemned the act as a "fearing anti-Semitic murder."
