TEHRAN, Iran (AP) — Iran's Supreme Leader Ayatollah Ali Khamenei says "there will be no talks with the U.S. at any level" — remarks apparently meant to end all speculation about a U.S.-Iran meeting at the U.N. later this month.

Iranian state TV on Tuesday quotes 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 has been speculation 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.

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