ISLAMABAD — Iranian Foreign Minister Abbas Araghchi is back in Islamabad on Sunday after having left Pakistan’s capital without meeting with US officials on Saturday, Pakistani and Iranian sources told The Post. It comes as the Pakistanis are working overtime to get a second round of US-Iran peace talks back on the table after President Trump cancelled American negotiators’ trip to Islamabad on Saturday. That abrupt cancellation came shortly after Araghchi and the Iranian delegation left Islamabad for Oman without meeting Special Envoy Steve Witkoff and Jared Kushner, who were expected to leave for Pakistan’s capital the same day.
