Witkoff leads third round of U.S.-Iran nuclear talks without breakthrough

U.S. Special Envoy Steve Witkoff led the third round of U.S.-Iran nuclear talks in Muscat, Oman on April 19, 2026, without Vice President Vance in attendance. The session produced no public agreement; U.S. officials said Iran had not accepted the administration's demand to reduce its stockpile of 60-percent-enriched uranium. Witkoff said the parties had agreed to meet again within two weeks.
