IDF tanks fired towards al-Kish Square in the Sheikh Sajeline neighborhood of southern Gaza City on September 20th, 2025, between 6:38 PM and 8:07 PM UTC, as warnings indicate over half a million residents have already fled the Gaza Strip. A video documenting the tank fire was published during this reporting window. Official statements regarding the specific IDF operations in Sheikh Sajeline were not immediately available. However, previous reports from earlier on September 20th detailed that the IDF struck over 100 terror targets across Gaza, Khan Yunis, and Rafah, with six additional fatalities reported in an earlier attack on Gaza City's Tuffah neighborhood. An IDF soldier was also moderately injured by sniper fire in Gaza City's Sheikh Radwan neighborhood earlier in the day. These operations continue against a backdrop of diplomatic tensions between Israel and Egypt concerning alleged Egyptian military expansion in the Sinai Peninsula, which Prime Minister Benjamin Netanyahu claims violate the 1979 Peace Agreement. Netanyahu presented details of these alleged breaches to U.S. Foreign Minister Marco Rubio on September 15th, 2025. The United Nations has also issued statements regarding humanitarian aid delivery, stating Israel must guarantee safe passage but is not permitted to secure or protect convoys. Previous reports noted that satellite imagery shared on social media reportedly geolocates Israeli military deployments, including Merkava Mk4 tanks and Namer Infantry Fighting Vehicles, near Egypt's border in Zone D of the Camp David Accords' security annex, which limits heavy armor, raising questions about potential Israeli treaty violations according to EGYOSINT. Human Rights Watch reported in March 2021 that the Egyptian army destroyed at least 12,350 buildings in the Sinai between late 2013 and July 2020. Separately, a Hamas militia attack injured five individuals, one critically, in Gaza at 1 a.m. last night.
