Israeli army chief Eyal Zamir said on Sunday that the "yellow line" demarcation is the "new borderline" inside the Gaza Strip, while sources reported that a Palestinian who crossed the line was killed on the same day. The "yellow line" marks the zone from which Israeli troops have not withdrawn in the Palestinian enclave, as part of the ceasefire arrangements that took effect on Oct. 10. "The 'yellow line' is a new borderline, serving as a forward defensive line for our communities and a line of operational activity," Zamir said during a visit to Beit Hanoun and Jabaliya in Gaza, where he met division commanders. He said the military has assumed "operational control over extensive parts of the Gaza Strip," adding that Israeli forces "will remain" in those areas. Zamir added the army "will not allow Hamas to reestablish itself" and is preparing for "surprise attack scenarios," which he described as a cornerstone of the military's upcoming multi-year plan. On Sunday, a Palestinian was killed Sunday by Israeli army fire in the Mawasi area of Rafah in southern Gaza. Ambulance and emergency services said the person was killed outside Israeli army deployment areas in Mawasi. The Israel Defense Forces said troops in southern Gaza "identified a terrorist who crossed the yellow line and approached the troops, posing an immediate threat", and that they "eliminated the terrorist". The Palestinian side has not yet responded. Since the October ceasefire, Gaza health authorities said Israeli attacks have killed 373 Palestinians and injured 970. Overall, since Oct. 7, 2023, Israeli attacks have killed 70,360 Palestinians and injured 171,047. SHOTLIST: FILE: Gaza City, Gaza Strip - Oct 20, 2025 1.
