Donald Trump canceled a planned trip by US officials to Pakistan for talks on the Iran war on Saturday, shortly after Tehran's delegation had left Islamabad. The US president said special envoy Steve Witkoff and son-in-law Jared Kushner would be wasting too much time, adding that if Iran wanted to talk all they have to do is call. Earlier, Iranian Foreign Minister Abbas Aragchi held talks with mediator Pakistan, mentioning he had shared Iran's position on ending the war but was uncertain whether the US was truly serious about diplomacy. Diplomatic efforts have stalled despite Trump's extension of a ceasefire set to expire on April 22 to facilitate discussions. Both parties remain in a standoff over the Strait of Hormuz, with Iran restricting movement through this critical shipping lane amid US-Israel military actions and concerns regarding Tehran's nuclear ambitions. Shortly before Trump announced the cancellation, the White House asserted that Iran was interested in talks, yet Iran refuted that a direct meeting was scheduled. Trump reiterated that the ceasefire would hold, despite diminished hopes for talks. He stated there was tremendous infighting and confusion within Iran's leadership, adding that \u201cif they want to talk, all they have to do is call!!!\u201d. The US has intensified its naval presence in the Strait to impede Iranian oil exports, intensifying longstanding tensions. Pakistan has mediated discussions between the U.S. and Iran over recent weeks, including an inconclusive meeting on April 11. Iran's President stated that while they remained open to negotiations, factors like breaches of commitments and threats hinder genuine talks. Countries like Oman and Russia are included in ongoing discussions led by Iran's foreign minister.
