Israel has begun constructing a network of new land barriers in the Gaza Strip, a move that has led to the displacement of Palestinian families and appears to be pushing the de facto border deeper into the territory. The barriers, primarily composed of large yellow concrete blocks and earthworks, have been moved westward into areas where civilians have been residing.

These developments come amidst ongoing conflict and raise questions about the long-term intentions of Israel's military presence in Gaza. The construction of these barriers follows an agreement brokered in October between Israel and Hamas, which stipulated that Israel would withdraw its forces to a designated demarcation line, referred to as the Yellow Line. This line was intended to leave Israel in temporary control of approximately 53% of Gaza's territory.

Families in the al-Tuffah neighborhood of northern Gaza were among the first to report the shift, waking on Monday to find the yellow concrete blocks moved westwards, encroaching on the Salah al-Din road, a crucial north-south artery. Nearby, an Israeli flag was seen flying atop an earth barrier approximately three meters high. The al-Shawish family, whose home was destroyed earlier in the war, were forced to flee again after a warning of an impending strike on a nearby building, losing their tent shelter in the process.

Experts observing the earthworks suggest they indicate a potential plan for a prolonged Israeli occupation of the strip. In some locations, these new earth barriers extend beyond the originally mapped Yellow Line, effectively widening a "no-go zone" for Gazans. One section near the al-Mawasi camp now sits over 1.5 kilometers beyond the original Yellow Line, while another in Khan Younis is positioned more than 500 meters past it.

Hamas has accused Israel of violating the October ceasefire agreement by moving the Yellow Line further into Gaza. However, a senior Israeli government official rejected these claims, stating that IDF deployments and security lines are operational measures taken to protect Israeli citizens and prevent Hamas from rebuilding its capabilities. The official added that Israel would continue to act against any ceasefire violations.

The Israeli military initially used concrete blocks to mark the Yellow Line. However, the construction of these new, extensive barriers began shortly after the ceasefire. The network now spans over 42 kilometers, covering 85% of the Yellow Line's intended path, with the longest single section extending 13.8 kilometers.

The IDF has stated its efforts are focused on clearly marking the Yellow Line's location to reduce friction. Previously, the military has denied claims that the Yellow Line has been moved or that IDF troops have crossed it. Nevertheless, other instances of displacement have been reported in Gaza in recent months as the yellow blocks have been repositioned further into the territory.

These actions by Israel have led to significant distress and displacement among families already struggling with the aftermath of the conflict. The shifting boundaries and increased security measures raise critical questions about humanitarian access, civilian safety, and the future stability of the region.
