President Donald Trump has abruptly called off planned U.S. travel to Pakistan for new peace talks with Iran - escalating uncertainty around ongoing negotiation.

In a post on Truth Social Saturday, Trump said he cancelled the trip to Islamabad, where U.S. officials were expected to meet Iranian representatives.

"I just cancelled the trip... Too much time wasted on traveling, too much work!" Trump wrote, adding there is "tremendous infighting and confusion" within Iran's leadership and claiming, "we have all the cards, they have none!"

The delegation was expected to include special envoy Steve Witkoff and Trump's son-in-law Jared Kushner. Iranian officials had declined to meet directly, instead opting for indirect talks through Pakistani mediators.

 Meanwhile:

  •  Iran's Foreign Minister Abbas Araghchi called earlier talks with Pakistan "very fruitful" and said Tehran proposed a framework to end the war
  •  Iran signaled it's unsure whether the U.S. is "truly serious about diplomacy"
  •  Tehran also warned it could launch the "largest missile strike in history" if attacked by the U.S. or Israel

Despite the tension, both sides are currently observing a ceasefire, recently extended by Trump.
