Tensions between Israel and Iran have escalated sharply following the killing of top Hamas and Hezbollah leaders, prompting fears of a wider Middle East conflict. Israel has intensified military actions against Iranian-backed groups, while Iran and its allies, including Hezbollah and Houthi rebels, have vowed retaliation. The U.S. and its allies are deploying additional military assets to the region to deter further escalation, with key diplomatic efforts underway to prevent an all-out war. U.S. Secretary of State Antony Blinken warned of imminent Iranian attacks, emphasizing the need for de-escalation. Despite these efforts, the region remains on high alert with Israel bracing for potential retaliatory strikes.
