U.S. and Iran presidents sign ceasefire agreement

Trump, attending the G7 with other leaders in France, also withdrew at least one of his stated rationales for attacking Iran in the first place, saying it would be "unfair" for Tehran not to have ballistic missiles, having previously ‌vowed to obliterate them.

"We're going to bomb the hell out of them if they violate the agreement," Trump said of Iran at a press conference. "I don't want them to. I want them to honor the agreement." He also called Iranians "smart people" as U.S. and Iranian negotiators work on a permanent truce over the coming 60 days, which Trump said he hoped would usher in peace in the Middle East and lower oil prices.

Earlier, he had said: "If I don't like it, if they don't behave, we'll go right back to dropping bombs right smack in the middle of their head, OK?"

Iran's leaders did not address the new threats while celebrating the ​moment, releasing photographs of what is believed to be the first agreement signed by both a U.S. and Iranian president since the Islamic Republic's founding in 1979.

"Everything we sought to achieve through military action, we obtained several times over through negotiation; it ​was not even comparable," Iran's lead negotiator Mohammad Baqer Qalibaf told state television about the agreement, which includes the unfreezing of billions of dollars in Iranian assets.

The U.S. and Israel launched the war on Iran ⁠on February 28, assassinating the 86-year-old Supreme Leader Ayatollah Ali Khamenei and military leaders on the first day. It quickly spiralled into a regional conflict that has killed more than 7,000 people, mostly in Iran and Lebanon; driven up energy prices; renewed inflationary pressures and sparked concerns about a ​major food supply crisis in developing countries.

The 14-point agreement extends a ceasefire announced in April by another 60 days, including in Lebanon, to allow the two sides to negotiate a final truce. Both Trump and Iranian President Masoud Pezeshkian have digitally signed the memorandum in English and Farsi, U.S. and Iran ​officials said, with Iran's foreign ministry saying the agreement was already in effect as of Wednesday.

Trump signed just before a grand dinner with French President Emmanuel Macron at the Palace of Versailles, the site of the signing of the eponymous treaty that formally ended World War One.

The memorandum includes an immediate end to the war on all fronts, including Lebanon, the full resumption of maritime traffic "with no charge" in the Strait of Hormuz, the lifting of a U.S. blockade of Iranian ports, the waiving of U.S. sanctions on Iran, the unfreezing of its assets, and a $300 billion investment fund for the Islamic Republic's post-war reconstruction.

Oil ​prices fell again on Wednesday on prospects for the reopening of the Hormuz, the slender, vital waterway between Iran and Oman, with Brent crude futures below $80, at their lowest level since the war's start. They later regained more than 1% after Trump threatened renewed violence.

Iran also undertakes not to ​build nuclear weapons, reaffirming a vow it had made for decades.
