Delegations from the United States and Iran have arrived in Switzerland for negotiations aimed at solidifying a provisional peace agreement between the two nations. The talks focus on ending the ongoing conflict, with Pakistan playing a key mediating role. The US Vice President arrived Sunday morning and expressed confidence regarding the discussions. Originally scheduled for Friday, the talks were postponed due to escalating tensions in the Middle East, specifically renewed clashes between Israel and Hezbollah. Despite a recently agreed-upon ceasefire between Israel and Hezbollah, further Israeli strikes prompted Iran to announce the closure of the Strait of Hormuz. These developments underscore the delicate context surrounding the peace negotiations.
