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.
