Mohammad Sinwar, a prominent Hamas military chief and brother of Yahya Sinwar, has reportedly been killed. He was elevated to his position in 2024 and was known for his role in clandestine operations, including the October 7, 2023 attack on Israel. Sinwar had survived multiple assassination attempts. His death is expected to lead to Izzeldeen Haddad taking command of Hamas' armed wing, though the broader impact on Hamas' decision-making and leadership influence remains unclear.
