# Negotiators from the United States and Iran were set to start peace talks in Switzerland on Sunday, even as US officials disputed Iranian claims about closing the key Strait of Hormuz. Although America and Iran had agreed to a 60-day ceasefire while negotiations take place, Tehran’s Islamic Revolutionary Guard Corps on Saturday declared the Strait of Hormuz shut. An adviser to Ayatollah Mojtaba Khamenei accused the US of failing to implement the first clause of its 14-point interim deal with Iran, which includes a ceasefire on all fronts, including Lebanon.
