Hamas Political Chief Ismail Haniyeh Assassinated in Tehran

Ismail Haniyeh, the head of the Hamas Political Bureau and the lead Hamas negotiator for ceasefire talks, is killed in an explosion at his residence in Tehran while attending the inauguration of Iranian President Masoud Pezeshkian. Iran and Hamas blame Israel; Israel does not officially confirm or deny responsibility. Haniyeh's assassination deals a major blow to ceasefire negotiations and triggers warnings of regional escalation from Iran and Hezbollah.
