Iran live updates: Iranian president pushes back at Trump during UN speech

Qatar mediated the meeting between U.S. and Iranian representatives on the sidelines of the United Nations General Assembly in New York on Tuesday, Iran's Foreign Minister Abbas Araghchi told Iranian state-run news agency IRNA.

Foreign Ministry spokesperson Esmaeil Baqaei told IRNA Tuesday night that his country conveyed its messages to the U.S. through Qatari mediation.

"The interaction that took place was through Qatari mediation. In fact, the Iranian delegation conveyed its views and conditions to the American side very clearly and explicitly through the mediators," Baqaei said.

The White House did not immediately respond to a request for comment.

The United Kingdom Maritime Trade Operations (UKMTO) Centre issued a warning advisory after it received a report of a vessel being struck by an unknown projectile in the Strait of Hormuz on Wednesday.

A company security officer reported the cargo ship was on fire and adrift, the advisory said. The crew was evacuated with two casualties reported.

Iranian President Masoud Pezeshkian is due to address the United Nations General Assembly on Wednesday, during the second day of this week's high-level event.

Pezeshkian's address comes on the heels of that of President Donald Trump, who on Tuesday said has he a "big decision to make" as to whether a deal will be made with Iran or whether he will "annihilate the Islamic Republic."

Top Iranian negotiator Mohamed Bagher Ghalibaf, the speaker of Iran's parliament, said on Wednesday before Trump's address that the president "can't impose his power on Iran."

Israeli Prime Minister Benjamin Netanyahu is also due to address the UNGA on Wednesday.

Special Envoy Steve Witkoff said that the U.S. and Iran engaged in indirect talks through “mediators” at the United Nations General Assembly in New York on Tuesday.

“Today, on the sidelines of the United Nations General Assembly, we engaged in lengthy talks with the Iranian delegation through the mediators, who shuttled between the two sides throughout the day,” Witkoff said in a post on social media Tuesday night.

Witkoff said that the unspecified mediators “successfully completed a round of discussions” and that their work will continue.

It’s unclear exactly who is mediating on behalf of the U.S. and who from the Iranian delegation participated.

Witkoff's readout comes after President Donald Trump told reporters on Tuesday that his aides met with the Iranian delegation -- though he declined to specify who. Later in the afternoon, Trump noted the meeting was actually with mediators.

Earlier in the day, Trump had represented to reporters that his aides had directly met with the Iranian delegation, replying “yes” when asked whether anyone from his team had met with them, and describing it as a three-hour meeting.
