Trump Says Doesn't Want 'Regime Change' In Iran, Cites Risk of Chaos

US President Donald Trump said Tuesday he didn't want to see "regime change" in Iran amid its conflict with Israel, adding that it would cause "chaos."

"If there was, there was, but no I don't want it. I'd like to see everything calm down as quickly as possible," Trump told reporters aboard Air Force One. "Regime change takes chaos, and ideally we don't want to see so much chaos."

Iran said that it was ready to return to negotiations with the United States, as a fragile ceasefire in its war with Israel took hold after 12 days of strikes that pummelled the Islamic republic's nuclear facilities.

But even as he appeared to express willingness to revisit nuclear talks derailed by Israel's surprise attack, Iranian President Masoud Pezeshkian said his country would continue to "assert its legitimate rights" to the peaceful use of atomic power.

The United States on Sunday had joined Israel's campaign with strikes on key nuclear sites.

After Iran retaliated with a missile attack Monday night targeting a US base in Qatar, President Donald Trump called for de-escalation, announcing the contours of a truce deal hours later.

Israel has said its war, which began on June 13, was aimed at preventing Iran from acquiring a nuclear weapon, an ambition Tehran has long denied holding.

After Trump angrily berated both sides for early violations of the truce on Tuesday, Tehran announced it would respect the terms of the deal if Israel did the same, while Israel said it had refrained from further strikes.

Both Israel and Iran appeared to claim victory following the announcement of the truce.

The Israeli government said Prime Minister Benjamin Netanyahu had convened his cabinet "to announce that Israel had achieved all the objectives of Operation Rising Lion and much more".

Iran's top security body, meanwhile, said the Islamic republic's forces had "compelled" Israel to "unilaterally" stand down.

While Iran and Israel have been locked in a shadow war for decades, it has been by far the most destructive confrontation between the arch-foes.

The war saw US strikes on Iranian nuclear sites using massive bunker-busting bombs, followed by an Iranian reprisal targeting the United States' largest military facility in the Middle East.

Trump shrugged off that response as "weak", thanking Tehran for giving advanced notice and announcing the outline of the ceasefire just hours later. 

Iran's National Security Council had said the number of missiles launched at the base "was the same as the number of bombs that the US had used" against Iran.

Israeli strikes on Iran have killed at least 610 civilians and wounded more than 4,700, according to the health ministry.

Iran's attacks on Israel have killed 28 people, according to official figures and rescuers.
