An American man was arrested at John F. Kennedy International Airport for plotting to bomb the US embassy in Israel.

Joseph Neumayer, a 28-year-old dual United States and German citizen, was charged with attempting to destroy, by means of fire or explosive, the Branch Office of the United States Embassy located in Tel Aviv, according to the Justice Department.

He arrived in Israel in April, then was detain after spitting on a security guard outside the embassy on May 19.

The Justice Department said Neumeyer broke free from the guard, but left behind his dark-colored backpack.

Investigators found three Molotov cocktails inside his bag then tracked him down to his hotel and arrested him.
