The assassination of Hamas leader Ismail Haniyeh in Tehran by Israeli airstrikes has heightened tensions in the Middle East, with experts warning of a potential all-out war. This incident follows Israel's earlier attempts to target a senior Hezbollah leader in Beirut and comes amid ongoing rocket attacks from Hezbollah into Israeli territory, which have resulted in civilian casualties. Israeli Prime Minister Benjamin Netanyahu has vowed a strong retaliation against Hezbollah, raising fears of a wider conflict that could involve Iran. The U.S. is concerned that escalating violence could jeopardize regional stability and negatively impact domestic politics ahead of upcoming elections. Iran has condemned the Israeli actions and warned against further military incursions, while Hezbollah denies involvement in the recent attacks. This volatile situation complicates ongoing efforts for a ceasefire between Israel and Hamas while risking a broader regional conflict.
