US Vice-President JD Vance arrived for peace talks with Iran at a Swiss mountaintop resort on Sunday as foreseen in a tentative peace deal, but the diplomacy was overshadowed by Iran's announcement that it had reimposed its blockade of the Strait of Hormuz.
A memorandum of understanding on a path to end the war, agreed a week ago, calls for the Strait to be reopened and a halt to all hostilities, including in Lebanon, which Washington's ally Israel invaded in March.
But with little sign of an end to fighting there, Iran said on Saturday it had shut the Strait again.
US officials have disputed that the Strait is closed and said 55 merchant ships had crossed it on Saturday. But on Sunday Iran's Fars news agency cited a military source as saying no new permits were being issued for ships to cross until further notice.
