WOODBURY - The U.S. State Department issued an international travel alert today for Americans staying overseas in the wake of a foiled terror plot targeting a Saudi diplomat.

As News 12 Long Island has reported, Manssor Arbabsiar and Gholam Shakuri, who is still at large, were charged yesterday with plotting to assassinate Saudi Arabia's ambassador to the U.S. at a Washington, D.C. restaurant.

According to President Barack Obama's administration, the plot was orchestrated by Iran. Officials say this grave provocation would have violated both U.S. and international law.

"This kind of reckless act undermines international norms and the international system," said Secretary of State Hillary Clinton. "Iran must be held accountable for its actions."

National security aides say the Obama administration will lobby to impose new international sanctions against Iran.
