The fragile Gaza ceasefire is now hanging by a thread after an Israeli airstrike on the Gaza coast killed Raad Saad, Hamas’s weapons chief marking the highest-profile assassination since the October truce. The strike has sent shockwaves through U.S.-brokered negotiations and pushed the ceasefire to its most dangerous moment yet. Hamas has confirmed Saad’s killing, accusing Israel of deliberately undermining the truce while rearmament allegations swirl in the background. As Phase Two negotiations stall, Gaza’s leadership has appealed directly to Trump and U.S. mediators, warning that the assassination fallout could collapse talks entirely. WATCH
