Ceasefire talks between Iran and the United States are set to take place in Islamabad, Pakistan, with both nations facing significant divisions over Lebanon and Iran's nuclear program. The US delegation, led by Vice President JD Vance, comes six weeks after a conflict triggered by US and Israeli strikes that killed Iranian Supreme Leader Ayatollah Ali Khamenei and resulted in thousands of deaths. The ceasefire, brokered by Pakistan, is already under strain, particularly regarding Israeli military actions in Lebanon, which have reportedly killed over 200 people. Iran's Foreign Minister Abbas Araghchi and parliament speaker Mohammad Bagher Ghalibaf lead the Iranian side, while US and Israeli representatives maintain that the ceasefire does not cover Israeli strikes in Lebanon. The negotiations will take place at the Serena Hotel in Islamabad, with officials from Pakistan facilitating discussions between the two delegations. Iran has warned it could withdraw from negotiations if the bombing in Lebanon persists.
