Airstrike under secret hospital complex aimed at eliminating Yahya Sinwar’s brother and key Hamas military operative, architect of the tunnel system and the current leader of the terror organization. No confirmation yet of his death, but there are signs of disarray and continuing IDF attacks around the compound.

On May 13, the Israel Defense Forces (IDF) executed a high-risk precision strike beneath a hospital compound in Khan Yunis, targeting Mohamed Sinwar, the brother of slain Hamas leader Yahya Sinwar and a senior commander within the terrorist organization. The operation marks Israel’s latest effort to dismantle Hamas’s remaining leadership in Gaza amid intensified military actions in the southern region.

According to Israeli defense officials, the strike utilized advanced bunker-busting munitions following concrete intelligence that Mohamed Sinwar had returned to a fortified Hamas command post beneath the Al-Mawasi area—previously designated by Israel as a humanitarian zone.

“We identified a high-value Hamas operative hiding in a fortified subterranean location. Based on verified intelligence, the Air Force struck the target with precision-guided munitions designed to penetrate hardened underground structures,” stated IDF Spokesperson Brig. Gen. Effie Defrin.

Mohamed Sinwar has long operated as Hamas’s military logistics chief in southern Gaza. While less visible than his brother Yahya—eliminated by Israel earlier in the war—Mohamed’s influence over tunnel operations, command coordination, and armed brigades in Khan Yunis has made him a high-priority target.

“Mohamed Sinwar is not a political figurehead. He’s a battlefield strategist, the man who turned Khan Yunis into a fortress,” said Maj. Gen. (res.) Amos Yadlin, former head of IDF Military Intelligence. “His death or capture would further erode Hamas’s ability to command and control forces in the south.”

The targeted site was reportedly under or adjacent to the Nasser Medical Complex, a location previously overrun by IDF ground units. IDF officials noted that Hamas has repeatedly used hospitals and humanitarian zones as covers for military activity—something Israeli intelligence believes was again the case in this operation.

“This strike should be seen in the broader context of our renewed campaign in Rafah and our dismantling of Hamas’s leadership hierarchy,” said Defense Minister Yoav Gallant. “If Mohamed Sinwar thought he could hide beneath a hospital, he was mistaken. There is no sanctuary for those responsible for the October 7 atrocities.”

As of Tuesday, the IDF has not confirmed whether Mohamed Sinwar was killed, though signals intelligence and aerial reconnaissance suggest high-value individuals were present during the strike. According to The Jerusalem Post, early indicators show significant structural collapse at the site, complicating recovery and verification efforts.

Military correspondent Nir Dvori of Channel 12 noted that the strike may also have taken out additional senior operatives who were convening at the location. “This was not a random hit. It followed weeks of observation and was timed to intercept a leadership gathering. The timing and depth of the strike point to a highly classified operational footprint,” he said.

Western security analysts say the targeting of Mohamed Sinwar is not only operational but psychological. “Israel is sending a message to Hamas: even in your deepest tunnels, you are being tracked,” said Jonathan Schanzer, senior vice president at the Foundation for Defense of Democracies in Washington. “Mohamed Sinwar may not have been the face of Hamas, but his elimination would be a major blow to their operational resilience.”

As of Tuesday morning, Hamas has not issued any formal statement regarding Mohamed Sinwar’s status, continuing a familiar pattern of ambiguity and information warfare. However, signs of disarray in Khan Yunis suggest the attack hit its intended mark—physically or psychologically.

With the IDF advancing in Rafah and striking high-value targets across Gaza, the pressure on Hamas’s surviving leadership continues to mount. And while Yahya Sinwar’s fate was sealed months ago, his brother may now have joined him beneath the rubble. Whether dead or on the run, Mohamed Sinwar is no longer operating with impunity.
