Who Was Marwan Issa, the Hamas Commander Killed by Israel?

Marwan Issa, the deputy commander of Hamas’s military wing in Gaza and a mastermind of the Oct. 7 assault on southern Israel, was confirmed dead on Monday by a senior U.S. official after an Israeli airstrike more than a week ago.

Jake Sullivan, the U.S. national security adviser, told reporters that Mr. Issa, one if the highest-ranking officials in Hamas, had been killed. Rear Adm. Daniel Hagari said on March 11 that Israeli military warplanes had targeted Mr. Issa and another senior Hamas official in an underground compound in central Gaza.

With his death, Mr. Issa who had been among Israel’s most wanted men, became the senior-most Hamas leader to be killed in Gaza since the start of the war. Israeli officials have characterized the strike as a breakthrough in their campaign to wipe out the Hamas leadership in Gaza.

But experts cautioned that his death would not have a devastating effect on Hamas’s leadership structure. Israel has killed Hamas’s political and military leaders in the past, only to see them quickly replaced.

Here is a closer look at Mr. Issa and what his death means for Hamas and its leadership.

What was Mr. Issa’s role in Hamas?

Mr. Issa, who was 58 or 59 at the time of his death, had served since 2012 as a deputy to Mohammed Deif, the elusive leader of the Qassam Brigades, Hamas’s military wing. Mr. Issa assumed the role after the assassination of another top commander, Ahmed al-Jabari.

Mr. Issa served both on Hamas’s military council and in its Gaza political office, overseen by Yahya Sinwar, the group’s highest-ranking official in the enclave. Mr. Issa was described by Palestinian analysts and former Israeli security officials as an important strategist who played a key role as a liaison between Hamas’s military and political leaders.
