“Hamas leader Ismail Haniyeh was assassinated early on Wednesday morning in Iran, the Palestinian militant group and Tehran said, drawing threats of revenge on Israel in a region already shaken by the war in Gaza and a deepening conflict in Lebanon. Iran's Revolutionary Guards confirmed the death of Haniyeh, hours after he attended a swearing in ceremony for the country's new president, and said it was investigating. Haniyeh, normally based in Qatar, has been the face of Hamas's international diplomacy as the war set off by the Hamas-led attack on Israel on Oct. 7 has raged in Gaza. Hamas' armed wing said in a statement Haniyeh's killing would "take the battle to new dimensions and have major repercussions", while Iran also vowed to retaliate. Iran's Supreme Leader Ali Khamenei said Israel had provided the grounds for "harsh punishment for itself" and it was Tehran's duty to avenge the Hamas leader's death as it had occurred in the Iranian capital.”
