Iran has vowed definitive and calculated retaliation against Israel for the assassination of Hamas leader Ismail Haniyeh in Tehran, which Iran attributes to Israel. Iranian Foreign Minister Abbas Araghchi and IRGC commander Hossein Salami both emphasized the nation's intent to respond, with Araghchi stating that Iran does not seek escalation but is prepared for it. Italy's Foreign Minister Antonio Tajani and other international leaders have called for restraint to avoid further regional instability. Concurrently, Israel and Hezbollah have engaged in significant military exchanges following the death of Hezbollah commander Fuad Shukr. High-level negotiations in Cairo involving the US, Egypt, and Qatar aim to mediate a ceasefire and hostage release between Israel and Hamas, though no final agreement has been reached.
