US foils Iran assassination plot

The United States accused Iran yesterday of backing a plot to kill the Saudi ambassador to Washington, escalating tensions with Tehran and stirring up a hornets’ nest in the Gulf, where Saudi Arabia and Iran have long jostled for power. US authorities said they had broken up a plot by two men linked to the Iranian government to assassinate Saudi Ambassador Adel al-Jubeir. One was arrested last month while the other was believed to be in Iran. Iran denies the accusations.
