IDF Constructs Massive Earth Barrier Dividing Gaza Strip in Two

Satellite images reveal that the Israel Defense Forces (IDF) have been building a large earth barrier that splits the Gaza Strip into two parts. According to an Associated Press report published on July 21, 2026, the barrier stretches over 23 kilometers along the "yellow line," separating the area under Israeli control, which comprises about half of the Gaza Strip, from the areas inhabited by Gazans. The IDF confirmed the construction to AP, emphasizing that it is located along the ceasefire line as part of the Gaza ceasefire agreement, but declined to specify how much longer the barrier will be extended.

The barrier has been constructed rapidly and quietly over recent months, with satellite images showing its length growing from approximately 500 meters on July 1 to 2.4 kilometers ten days later. The southern section of the barrier, which began construction in February, extends from Rafah to Al-Mawasi, where displaced Gazans' tent camps have been established. If construction continues at the current pace, the barrier could eventually stretch 17 kilometers from Khan Yunis to Gaza City in the north.

Alongside the earth barrier, a security zone equipped with intelligence and technological assets has been established around the yellow line. Satellite images also show some unconnected segments near Beit Lahia, though the height of the barrier remains unclear.

Meanwhile, the IDF and Shin Bet continue operations in Gaza targeting Hamas militants. On the morning of the report, the IDF announced the killing of Adham Ibrahim Shaaban Nesman, head of operations for Hamas's Gaza City Brigade. Nesman was responsible for directing the October 7 attacks into Israel and held numerous Israeli hostages, including Rumi Gonen, Emily Damari, and others. He was also involved in training militants and restoring Hamas's military capabilities, actions the IDF said violated the ceasefire agreement.

Emily Damari, a former hostage, commented on Nesman's death on Instagram, describing him as a serious and dangerous figure among Hamas militants during her captivity.
