U.S. envoy Steve Witkoff and Jared Kushner will be in Doha to meet Qatari mediators to discuss U.S.-Iran negotiations, Qatar's foreign ministry spokesperson said on Tuesday. There will not be a high-level meeting between Washington and Tehran, Majed Al Ansari told a media briefing, adding that Qatar has not transferred $6 billion of Iranian frozen funds to Tehran. Doha has been coordinating with Oman, which sits on the western coast of the Strait of Hormuz, on the safe passage for vessels.
