Key mediator Pakistan said technical-level talks will begin on Sunday in Burgenstock, Switzerland, with Qatari mediators also participating. WATCH: Israel and Hezbollah agree to a ceasefire as deadly fighting threatens U.S.-Iran deal Iran's joint military command said the strait was closed because of the U.S. "clear breach of its commitments" by failing to end the war. The interim deal is meant to stop fighting on all fronts. Shortly after that, the state broadcaster said Iran's negotiating team was leaving for Switzerland, a trip originally planned for Friday. State media said the team includes parliamentary Speaker Mohammad Bagher Qalibaf, Foreign Minister Abbas Araghchi and central bank and oil officials, among others. The U.S. disputed Iran's announcement on the strait. "Iran does not control the Strait of Hormuz. Traffic continues to flow, and U.S. forces are monitoring the situation to ensure this remains the case," said Capt. Tim Hawkins, a spokesperson for U.S. Central Command. The military said 55 merchant ships transited Saturday with more than 17 million barrels of oil. Iran's team departs for talks as uncertainty grows Foreign Ministry spokesperson Esmail Bagahei signaled that little might happen in talks until Iran feels the U.S. is living up to the deal. Negotiations toward a final agreement will begin only once key commitments are upheld, Bagahei said. If they are not, "the memorandum of understanding as a whole will be jeopardized."

The interim deal gives negotiators 60 days to reach a nuclear agreement, but that can be extended. Vance told Fox News that he expects to leave for Switzerland in "the next couple of days" but acknowledged that "it's always a delicate coordination dance."
