Iran Says 'Ready to Examine' U.S. Plot Accusations

Iran is "ready to examine" information the United States says supports accusations Tehran plotted to kill the Saudi ambassador to Washington, Foreign Minister Ali Akbar Salehi said Monday.

"We are ready to examine with deliberation any issue, even if it was fabricated. We have asked America to provide us with information of this scenario," Salehi was quoted as saying by the official IRNA news agency.

Iran has sent a letter to U.S. authorities via the Swiss embassy in Tehran asking for information about an Iranian-American in U.S. custody accused of being at the center of the alleged plot. It also demanded consular access to the suspect.

Iranian officials and leaders have fiercely denied any involvement in the alleged plot, calling it an attempt by Washington to divert attention from domestic economic woes and foreign policy failures in the Middle East.

The denials have become louder as the United States has made moves to rally other nations to a bid to further isolate Iran, which is already subject to severe economic sanctions over its controversial nuclear program.

Iran's supreme leader, Ayatollah Ali Khamenei, warned Sunday that "any inappropriate action -- whether political or security-related -- will meet with the Iranian people's decisive response."

The head of the U.S. Senate Intelligence Committee, Dianne Feinstein, said after that warning that the United States and an "increasingly hostile" Iran were on a "collision course."

The two countries broke off diplomatic ties three decades ago, ever since Islamic students in Tehran took U.S. diplomats hostage following Iran's revolution. Today they are arch-foes battling for influence over the Middle East.

"The Americans wanted to stir up an issue in the public opinion and take advantage of the consequent political hue-and-cry to concoct lies about our country. (But) the scenario lacks solid bases," Salehi was quoted as saying.

He denied repeated U.S. accusations that Tehran sponsored terrorism, and said, according to the state television website: "The Islamic Republic of Iran is a country committed to its international obligations, and it will defend its rights under international law."

The United States says the chief suspect it has charged, an Iranian used-car salesman who is a naturalized U.S. citizen living in Texas, Manssor Arbabsiar, confessed to acting as an agent for his cousin, whom he described as a high-ranking official in the Quds Force that forms part of Iran's Revolutionary Guards.

Arbabsiar, described by those who knew him as a talkative but absent-minded man, is alleged to have tried to contract a Mexican drug cartel to assassinate the Saudi ambassador, Adel al-Jubeir, possibly through the bombing of a Washington restaurant.

But, according to U.S. officials, Arbabsiar's contact in the cartel was a paid FBI informant who raised the alert.

The U.S. Justice Department's criminal complaint against Arbabsiar alleged that high-ranking Quds Force officials transferred nearly $100,000 to the informant's bank account as down payment for the $1.5-million-dollar hit.

The man U.S. officials say was Arbabsiar's main face-to-face contact in the Quds Force, Gholam Shakuri, alleged to be an aide to Arbabsiar's cousin, was also charged with trying to murder a foreign dignitary with a "weapon of mass destruction."

However Shakuri was not in U.S. custody, and was believed to be in Iran.

U.S. President Barack Obama has vowed Iran will "pay a price" for the alleged assassination plan.

Saudi Arabia has also said it will make "a suitable response" and requested the matter be brought before the UN Security Council.

Britain and France have said they will back any measure to punish Iran on the issue.
