Analyst H.A. Hellyer on how Hamas leader's death will destabilise tensions in the Middle East

US Secretary of State Antony Blinken said Washington was unaware of and not involved in the air strike that killed Hamas leader Ismail Haniyeh. The Hamas chief was in Iran for the inauguration of new president Masoud Pezeshkian. His death has threatened to deepen the war in Gaza, with Hamas, Iran and their allies vowing swift retaliation. Dr H.A. Hellyer, a senior associate fellow at the Royal United Services Institute for Defence and Security Studies, shared how Haniyeh's death will destabilise tensions in the Middle East further.
