President Donald Trump in about eight hours went from suggesting a nuclear deal with Iran remained "achievable" to urging Tehran's 9.5 million residents to flee for their lives as he cut short his visit to an international summit to return to Washington for urgent talks with his national security team.

Trump arrived at the White House early Tuesday at a moment of choosing in his presidency. Israel, with five days of missile strikes, has done considerable damage to Iran and believes it can now deal a permanent blow to Tehran's nuclear program — particularly if it gets a little more help from the Republican president.

Israel stunned and hobbled Iran last week when it pulled off an intelligence and military operation years in the making that struck high-level targets with precision.

Guided by spies and artificial intelligence, the Israeli military unleashed a nighttime fusillade of warplanes and armed drones smuggled into Iran to quickly incapacitate many of its air defenses and missile systems. With greater freedom to fly over Iran, Israel bombarded key nuclear sites and killed top generals and scientists. By the time Iran mustered a response hours later, its ability to retaliate — already weakened by past Israeli strikes — was greatly diminished.

There appear to have been "direct impacts" on the underground part of Iran's Natanz nuclear site during Israel's attacks, the U.N.'s atomic watchdog said on Tuesday.

"Based on continued analysis of high resolution satellite imagery collected after Friday's attacks, the IAEA has identified additional elements that indicate direct impacts on the underground enrichment halls at Natanz," the International Atomic Energy Agency said on X, formerly Twitter.

Iran's Revolutionary Guards said they struck a center of Mossad, Israel's foreign intelligence service, in Tel Aviv on Tuesday, amid an escalating air war between the two foes.

In a statement aired on state television, the Guards said they "struck the military intelligence centre of the Zionist regime's army, Aman, and the Zionist regime's terrorist operations planning centre, the Mossad, in Tel Aviv", adding it was "currently on fire".

U.S. President Donald Trump said Tuesday he was aiming for a "real end" to the conflict between arch-rivals Israel and Iran, and not just a ceasefire.

"I'm not looking for a ceasefire, we're looking at better than a ceasefire," Trump told reporters on board Air Force One before arriving back in the United States from a G7 summit in Canada.

Iran's Foreign Minister and chief nuclear negotiator Abbas Araghchi said Israel's strikes against his country "deal a blow" to diplomacy during a call Monday with his French, British, and German counterparts.

"The Israeli aggression against Iran in the midst of nuclear negotiations with the United States is a blow to diplomacy," Abbas Araghchi said during a call reported by his ministry with French Foreign Minister Jean-Noel Barrot, the United Kingdom's David Lammy, Germany's Johann Wadephul, and the European Union's head of foreign affairs Kaja Kallas.

U.S. President Donald Trump left a G7 summit in Canada a day early on Monday, heading back to the White House as Israel and Iran traded missile fire for a fifth straight day.

Trump's helicopter lifted off from the summit venue in the Canadian Rockies to take him to his plane, shortly after he warned residents to evacuate the Iranian capital Tehran.

A Russian attack on Ukraine's capital killed at least 14 people, the head of Kyiv's military administration said Tuesday.

"According to initial reports, there are already 14 deaths in Kyiv," Tymur Tkachenko wrote on Telegram, adding that rescuers were still searching the rubble for victims.

TIsrael's strikes on the headquarters of Iran's state television in Tehran killed three people, the broadcaster said on Tuesday, a day after the attack.

"Three of the TV station's employees were killed and others were wounded in the Israeli attack" on Monday, the channel announced, without specifying the number of people hospitalized.

The White House is discussing with Iran the possibility of a meeting this week between U.S. envoy Steve Witkoff and Iranian Foreign Minister Abbas Araghchi, four sources briefed on the issue told U.S. news portal Axios.
