"They will forgive, but they will never forget what Iran has done."

Iranian Foreign Minister Abbas Araghchi did the quick turn-around after leaving Pakistan's capital without meeting with US officials Saturday, a move that prompted Trump to then swiftly cancel American negotiators' intended trip to Islamabad.

President Trump has called off sending a US delegation to Pakistan Saturday for peace talks with Iran – canceling a trip he said would be a waste of time.

US special envoys Steve Witkoff and Jared Kushner will travel to Pakistan this weekend for additional peace talks with Iran, White House press secretary Karoline Leavitt confirmed Friday.

Iranian Foreign Minister Abbas Araghchi will lead a "small delegation" to Islamabad, which is set to arrive around 10 p.m. local time, an Iranian source said.

The uncertainty is especially apparent in Islamabad, which hosted the first round of talks and is expected to hold the second round soon.
