Evidence that Iran was behind a plot to kill the Saudi Arabian ambassador to Washington is overwhelming, a former chief of Saudi intelligence services said on Wednesday.
"The burden of proof is overwhelming ... and clearly shows official Iranian responsibility for this. Somebody in Iran will have to pay the price," Saudi Prince Turki al-Faisal said.
U.S. authorities said on Tuesday they had broken up a plot by two men linked to Iran's security agencies to assassinate Saudi Ambassador Adel al-Jubeir. One was arrested last month while the other was believed to be in Iran.
Iran has denied the charges and expressed outrage at the accusations.
