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.

Israel's assassination of a senior Hamas commander threatens the viability of the Gaza ceasefire, the chief negotiator of the militant group said on Sunday, calling on U.S. President Donald Trump to demand Israel comply with the terms of the truce.

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

Israeli Prime Minister Benjamin Netanyahu also announced President Trump will receive the Israel Prize for his work on peace negotiations.

An explosive device has detonated in Gaza and wounded one Israeli soldier, prompting Israel to accuse Hamas of violating the U.S.-brokered ceasefire

Israel and Hamas have been trading accusations of ceasefire breaches since the US-brokered ceasefire began in October

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.

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