Iran’s supreme leader announced on Tuesday that “there will be no talks with the U.S. at any level” — remarks apparently meant to end all speculation about a possible U.S.-Iran meeting between the two countries’ presidents at the U.N. later this month.

Iranian state TV quoted Ayatollah Ali Khamenei as saying this is the position of the entire leadership of the country and that “all officials in the Islamic Republic unanimously believe” this.

“There will be no talks with the U.S. at any level,” he said.

Khamenei said the U.S. wants to prove its “maximum pressure policy” against Iran is successful.

“In return, we have to prove that the policy is not worth a penny for the Iranian nation,” Khamenei said. “That’s why all Iranian officials, from the president and the foreign minister to all others have announced that we do not negotiate (with the U.S.) either bilaterally or multilaterally.”

There had been reports about a possible meeting between President Donald Trump and his Iranian counterpart, Hassan Rouhani, during the upcoming U.N. General Assembly this month in New York.

But tensions roiling the Persian Gulf have escalated following a weekend attack on major oil sites in Saudi Arabia that the U.S. alleged Iran was responsible for — a charge Iran denies.

The crisis between Washington and Tehran stems from Trump’s pullout last year from the 2015 nuclear deal between Iran and world powers. He also re-imposed and escalated sanctions on Iran that sent the country’s economy into freefall. Read more
