Hamas has confirmed that its longtime spokesman was killed following an Israeli strike in August in war-torn Gaza.

Five Hamas military commanders confirmed dead by terrorist group's armed wing, marking significant blow to Palestinian militant organization's leadership structure in Gaza conflict.

The senior leaders killed included Mohammad Sinwar, Hakham Muhammad Issa al-Issa, Mohammed Shabana, and Ra’ad Sa’ad. Sinwar was the brother of former Hamas chief Yahya al-Sinwar. Sinwar was killed roughly a year after the Oct. 7 terror attack.

Several international humanitarian organizations, including Doctors Without Borders (MSF), face being barred from working in Gaza from Thursday for failing to comply with Israel’s new restrictions for aid groups working in the devastated enclave.

The legislation was the latest blow to the agency, known as UNRWA. Israel has accused it of being extensively infiltrated by Hamas.
