The Middle East is on edge as Iran vows to retaliate against Israel following the death of Ayatollah Ali Khamenei, the country's supreme leader and a vocal critic of the West and Israel. The tension escalated over the weekend, with Iran launching attacks across the region, including in Israel and the Persian Gulf, as well as an unprecedented strike against Oman, a key mediator in nuclear talks between the U.S. and Iran. These strikes came in response to a U.S.-Israeli attack that killed Khamenei and other top Iranian leaders, marking a significant escalation in the conflict. The aftermath has been a mix of grief and celebration in Iran, with the government declaring 40 days of mourning and establishing a temporary leadership structure. Israeli defense officials claim their initial strikes eliminated 40 military commanders and vowed to continue dismantling Iranian military infrastructure. The situation remains volatile, with the potential for further retaliation and a broader regional conflict.
