According to the IDF, Hakham Muhammad Issa Al-Issa was "one of the last remaining senior Hamas terrorists" in Gaza

The Israel Defense Forces (IDF) said on Saturday it "eliminated" Hakham Muhammad Issa Al-Issa, described as one of the founders of Hamas' military wing and a mastermind of the deadly October 7, 2023 incursion into Israel.

The surprise attack by the Palestinian militants left around 1,200 people dead, with 250 taken hostage. In response, Israel launched a massive military campaign against Hamas in Gaza. The IDF has subjected the densely-populated Palestinian enclave to severe artillery bombardment and airstrikes, reducing much of it to rubble.

According to the IDF, Issa, who "led Hamas' force build-up, training, and planned the October 7 massacre," was killed in Gaza on Friday.

He "served as Head of the Combat Support Headquarters, and advanced aerial and naval terrorist attacks against Israeli civilians and IDF troops operating in the Gaza Strip," it claimed in a statement on Telegram.

Issa served as "Head of the Training Headquarters, and was a member of Hamas' General Security Council," the IDF added.

According to media reports, the Hamas commander was killed in an airstrike, along with his wife and grandson.

Late last month, the IDF confirmed the killing of Hamas leader Muhammad Sinwar in an airstrike conducted on May 13 in the southern Gaza city of Khan Younis. According to the statement, the strike obliterated an "underground command and control center, under the European Hospital in Khan Younis," where the Hamas leader was holed up, along with several high-ranking operatives.

Hamas has repeatedly denied Israeli claims that it places its military facilities in the midst of residential areas or civilian infrastructure.

Last December, Israeli Defense Minister Israel Katz claimed responsibility for the assassination of Hamas political chief Ismail Haniyeh in Tehran in late July 2024. Haniyeh, who was the Palestinian armed group's chief negotiator in indirect ceasefire talks with Israel, was killed by an explosive device.

Israel intensified its ground offensive in Gaza in May after negotiations over the fate of the remaining hostages in Hamas' captivity stalled.

During the course of the hostilities in Gaza, more than 55,600 Palestinians, mostly civilians, have lost their lives, according to the enclave's Hamas-controlled health authorities.
