All over Iran people cheered on announcement of Khamenei death, Trump says

Ukrainian President Volodymyr Zelensky said on Sunday that Ukraine is closely watching every development around Iran, with intelligence and foreign ministry fully engaged and actions coordinated with partners.

Zelensky said the need to use this opportunity for real change in Iran, supporting the Iranian people against a regime that has killed tens of thousands of its citizens, fueled regional wars and supplied Shahed drones to Russia. He called for clear international backing for the people and human lives.

The Institute for Science and International Security reported on Sunday strikes near Iran's Atomic Energy Organization (AEOI) headquarters in Tehran, home to the Tehran Nuclear Research Center and its small research reactor.

“The reactor is not expected to be targeted by Israel or the US as satellite imagery shows no signs of damage. In June last year attacks, Israel struck nearby internal security forces and centrifuge manufacturing sites," the post said.

Donald Trump remained open to more talks with the Iranians but could not say whether they would happen “soon,” the Daily Mail reported on Sunday, citing an interview with the US president.

“I don’t know,” the Daily Mail quoted Trump as saying. “They want to, they want to talk, but I said you should have talked last week, not this week.”

Trump also outlined a potential timeline for the war with Iran, suggesting the fighting could continue for the next four weeks.

“It’s always been a four week process. We figured it will be four weeks or so. It’s always been about a four week process, so as strong as it is, it’s a big country, it’ll take four weeks or less,” Trump said.

A senior White House official said on Sunday Iran's potential new leadership has indicated readiness to negotiate with the United States after US-Israeli strikes killed Supreme Leader Ali Khamenei and other top officials.

The unnamed official told the Associated Press that President Donald Trump is willing to negotiate “eventually” but military operations will continue without pause for now.

The official did not identify the potential new leaders.

Iran's Foreign Minister Abbas Araghchi said on Sunday that the bombings in Tehran have no impact on the country's ability to conduct war.

“We've had two decades to study defeats of the US military to our immediate east and west. We've incorporated lessons accordingly,” he posted on X. “Bombings in our capital have no impact on our ability to conduct war. Decentralized Mosaic Defense enables us to decide when - and how - the war will end.”
