Iran Update, December 31, 2023
December 31, 2023 - ISW PressIsraeli forces advanced into Beit Lahiya for clearing operations in the northern Gaza Strip. An Israeli Brigade Combat Team identified three Hamas fighters inside a building and directed an airstrike at their position in Beit Lahiya, according to an IDF report on December 31. The al Qassem Brigades—the militant wing of Hamas—intercepted an Israeli reconnaissance drone in Beit Lahiya on December 31. Israeli forces initially advanced into the Gaza Strip west of Beit Lahiya in late October. Commercially available satellite imagery captured on December 31 shows recently flattened terrain in Beit Lahiya City and north of the city, which suggests that Israeli tanks or bulldozers recently began operating in the area. The Wall Street Journal published a map of the tunnel system that Hamas has created below the Gaza Strip based on data from 2014, which includes an extensive tunnel network in Beit Lahiya. Palestinian militia fighters have used tunnel shafts to maneuver through the strip and to ambush Israeli forces. The IDF has located about 1,500 tunnel shafts and routes in the Gaza Strip since the beginning of the ground operation in the Gaza Strip, according to an IDF report on December 19.
