The killing of Hamas's political leader in an attack blamed on Israel has heightened concerns of a broader regional conflict and disrupted efforts to end the long-running Gaza war. Qatar's mediation efforts with Hamas have been impacted, with doubts raised over the future of talks following the assassination of the Palestinian negotiator. Netanyahu's alleged obstruction of a Gaza ceasefire has further complicated negotiations, with recent talks in Cairo failing to yield progress.
