Iran reiterates support for Hezbollah and links any broader ceasefire or peace steps with the United States to developments in Lebanon, according to multiple outlets. Iran demands Israel withdraw from southern Lebanon and says a ceasefire between Israel and Hezbollah is a condition for any wider deal with Washington, as fighting continues for a fourth month. In parallel, two semiofficial Iranian news agencies, Fars and Tasnim, report that Iran stops communicating with mediators after Israel threatened to bomb Beirut amid ongoing hostilities involving the Iranian-backed militia Hezbollah. A regional official involved in mediation, speaking anonymously, says Iran does not communicate at all on Tuesday after stating that a ceasefire must be enforced in Lebanon for negotiations to continue. Other reports note that Israel and the United States describe the Lebanon fighting as separate from the wider Iran-U.S. talks, while Iran presents the conflict as connected. The reporting also indicates the negotiations involve pressure related to a potential Iran-U.S. ceasefire and access affecting shipping through the Strait of Hormuz.
