Iranian leadership has not confirmed claim, after the US president announced that planned strikes on Iran had been cancelled

Donald Trump claimed on Thursday that Washington and Tehran were on the verge of signing a peace agreement, and announced that he was cancelling fresh missile strikes, after two days of escalating attacks on Iran that threatened to collapse the fragile ceasefire.

His comments followed a new bout of public diplomacy by social media, but were dismissed by Iran’s foreign ministry, which said a final decision on an agreement had not been reached.

The US launched a new round of airstrikes on Iran into Thursday morning after Donald Trump warned Tehran would “pay the price” for stalled negotiations, prompting Iran to respond with strikes targeting Bahrain, Kuwait and Jordan.

The new US assault across a range of Iranian cities came as efforts to negotiate an end to the war again appeared stuck, with Iran insisting it would maintain its chokehold on the strait of Hormuz. The American attack appeared more intense and wider than the day before, but Iran released no information about what was hit.
