Haniyeh's death has been seen as a significant blow to Hamas amid the war. His death is the second report of a Hamas leader assassination. Hezbollah's most senior military commander, Fu'ad Shukr, was reportedly killed Tuesday in a strike in Beirut, Lebanon, the Israel Defense Forces said. Hamas has not yet confirmed his death.

The assassination of Hamas political leader Ismail Haniyeh in the Iranian capital Tehran has rocked the Middle East, threatening to further destabilize the region and jeopardize ceasefire negotiations between Israel and Hamas over the war in Gaza.
