Iranian President Masoud Pezeshkian delivered a defiant speech to the United Nations General Assembly on Wednesday, condemning President Trump’s threat to “annihilate” his country, while calling for diplomacy to end the war.

President Masoud Pezeshkian: “America and Israel attacked us equipped with the latest technology and weapon systems, and our people stood steadfast. Yes, they did hit us, but we did not bend the knee. We did not bow our head. We responded, but we did not hit civilian populations. They came into surrounding territories and targeted our universities, our healthcare centers, our schools, our hospitals, our infrastructures — all of it against international law.”

A lone U.S. delegate walked out of the U.N. hall in protest as President Pezeshkian spoke; Israel’s ambassador boycotted the speech entirely.
