Hamas leader Ismail Haniyeh will be buried in Qatar following his assassination in Tehran, an attack attributed to Israel that has escalated tensions in the region. Haniyeh, who played a significant role in negotiations between Hamas and Israel, was killed alongside a bodyguard during a pre-dawn strike. His funeral will take place at the Imam Muhammad bin Abdul Wahhab mosque in Doha, with many mourners expected to don Palestinian flags as they pay their respects. Hamas has called for a 'day of furious rage' coinciding with the burial, and Turkey and Pakistan have declared a day of mourning. The assassination has raised concerns over further conflict involving Iranian-backed groups in the Middle East, as calls for revenge echo across the region. Israel has not commented on the incident directly, amidst ongoing hostilities in Gaza and recent attacks on Hezbollah leaders.
