A dual U.S.-German citizen has been arrested on charges that he traveled to Israel and attempted to firebomb the U.S. Embassy branch office in Tel Aviv.

Rodriguez’s charges were laid out in a criminal complaint. He was informed by U.S. Magistrate Judge Matthew Sharbaugh during an initial appearance in federal court Thursday that some of the charges against him carry the possibility of the death penalty or life in prison, officials said in the briefing later that afternoon.
