Track updates on Iran US warHe said Iran's armed forces had rebuilt their capabilities during the ceasefire and that, if the United States "foolishly restarts the war", the consequences would be "more forceful and bitter" than at the start of the conflict."Our armed forces have rebuilt themselves during the ceasefire period in such a way that if Trump commits another act of folly and restarts the war, it will certainly be more crushing and bitter for the United States than on the first day of the war," Ghalibaf posted on social media, news agency AFP reported.Iran's warning of a crushing response to US comes amid reports suggesting that the White House is considering renewed strikes.US intel on Iran rebuilding its armed forcesA few days ago, a CNN report indicated that Iran reportedly has resumed some of its drone production after nearly six weeks of war heavily impacted its military capabilities.Also read: Over 1.2 million Indian-American families in limbo: Former White House advisor as US tightens Green Card processThe report, citing sources, said that Iran has already restarted some of its drone production during the pause in fighting that began on April 8 and Iran could fully reconstitute its drone attack capability in as soon as six months.This indicates that Iran is quickly rebuilding its military capabilities that were hit badly by US-Israeli strikes, the report said, quoting sources familiar with US intelligence assessments.

He was meeting Pakistan's army chief Asim Munir when he made the remarks as diplomatic efforts to end the war have intensified with Pakistan placing itself as a mediator.Iranian state media reported that Munir had also met President Masoud Pezeshkian in the presence of foreign minister Abbas Araghchi, with whom he had two meetings, before flying out.The talks reportedly centred on a 14-point document proposed by Iran, which it considers the main framework for the discussions, and messages exchanged between the two sides.Ghalibaf said Iran would pursue its "legitimate rights", both on the battlefield and through diplomacy, but added that it could not trust "a party that has no honesty at all", an allegation Iran has made several times before.
