Times of Israel: "Channel 12 cites a senior Israeli official who it says has confirmed that Hamas leader Yahya Sinwar has been eliminated." Political observer Michael Horowitz notes on X: "If Sinwar has been killed, a key question is the fate of his brother - who might be his successor". Yahya Sinwar's younger brother, Mohammed, has risen in prominence following the killing of Hamas' military chief Mohammed Deif in a July airstrike. Mohammed Sinwar is strongly associated with Hamas' military wing and is seen as a key architect of the 7 Oct attacks on Israel alongside his brother.
