Hamas did not provide details on Sinwar’s death but published pictures of him along with other group leaders, describing them as “martyrs”.

Mohammad Sinwar was the younger brother of Yahya Sinwar, the faction’s chief, who co-masterminded the October 7, 2023, attack on Israel, and whom Israel had killed in combat a year later.

He was elevated to the top ranks of the group after the death of his brother.

His confirmed death would leave his close associate Izz Al Din Haddad, who currently oversees operations in northern Gaza, in charge of Hamas across the whole of the enclave.
