Israel moves Yellow Line deeper into Gaza, satellite images show
Quick Summary
A BBC Verify investigation has found that Israeli forces are pushing the post-ceasefire "Yellow Line" boundary deeper into Gaza, creating a dangerous and confusing reality for Palestinians despite official IDF denials. Satellite evidence shows concrete blocks marking the line have been moved hundreds of meters further into Palestinian territory in multiple locations, such as Gaza City and Jabalia, while other areas remain completely unmarked. This shifting boundary has a severe human cost, with Gazans feeling trapped and reporting direct fire, shelling, and constant drone surveillance. The investigation highlights numerous fatal incidents, including a strike on a school shelter that killed five, the killing of a 17-year-old boy by a tank, and the shooting of two young children gathering firewood, all in areas that were supposed to be safe. While one expert views this as deliberate "territorial engineering" to create a flexible buffer zone, another suggests it may be for practical convenience. These incursions are accompanied by armored bulldozers and the widespread demolition of buildings, which the IDF claims is to destroy Hamas tunnels. Ultimately, the physical placement of these blocks, not the official ceasefire map, dictates the de facto border, allowing Israel to carve out a "sterilised belt" and leaving Palestinians in a constant state of peril and uncertainty.

A BBC Verify investigation has found that Israeli forces are pushing the post-ceasefire boundary deeper into Gaza, creating a confusing and dangerous reality for Palestinians. Satellite photos show a clear pattern: in at least three locations, troops first laid down yellow concrete blocks to mark the line of control, only to move them further into Palestinian territory later on.
This "Yellow Line," established on Israeli military maps through a US-negotiated deal with Hamas, comes with a deadly warning. Back in October, Defence Minister Israel Katz declared that anyone crossing it would be "met with fire"—a threat that has since been followed by numerous fatal incidents.
Satellite imagery tells a troubling story. In Gaza City's al-Tuffah neighborhood, photos taken between late November and Christmas show at least seven concrete blocks being shifted deeper into Gaza. In other areas like Beit Lahia and Jabalia, these markers have been pushed an average of 295 meters (968 feet) into the Strip. After mapping another 205 markers, BBC Verify found that more than half were placed well inside the boundary shown on official maps.
Despite the visual evidence, an IDF spokesperson denied "all claims that the Yellow Line has been moved," insisting that soldiers were simply marking the line "in accordance with the conditions on the ground." Yet, photos from as recently as January 11 show that a nearly 10-kilometer (six-mile) stretch of what Israel's own military chief calls a "new border line" has no markers at all, leaving Gazans to guess where the "dangerous combat zone" actually begins.
The human cost of this shifting line was laid bare by a 23-year-old man near Khan Younis, who told the BBC he felt "trapped" after troops suddenly moved the concrete blocks past the official line last month. "We are now living inside the Yellow Line, but behind the yellow blocks, with no idea what our fate will be," he said, speaking anonymously for his own safety. He described his nights as a terrifying ordeal of exploding shells, advancing soldiers, and the constant hum of drones. "We are also being shot at directly," he added. His experience isn't unique; a review of the IDF's own statements reveals at least 69 separate incidents where troops opened fire on people near the Yellow Line since the warning was issued.
One of those attacks, on December 19th, struck a school in Gaza City's al-Tuffah neighborhood being used as a shelter for displaced families. According to IDF maps, the school was 330 meters inside the Palestinian side of the line, but it was just feet from a yellow block that had been moved. Witnesses said a wedding was happening next to the school when an explosion killed five people, including children. The IDF later stated it had fired on "suspicious individuals" and that the incident was under review.
Just days earlier, 17-year-old Zaher Nasser Shamiya was killed near the concrete blocks in the Jabalia camp. His father gave a horrifying account, saying that IDF soldiers shot his son before a tank "turned his body into pieces" in what was supposed to be a safe area. In another incident, two young children, around eight and ten years old, were killed while gathering firewood for their disabled father. The IDF reported it had "eliminated two suspects" for crossing the line and engaging in "suspicious activities," but didn't explain how the children were considered a threat.
Experts are split on the motivation behind these moves. Professor Andreas Krieg, a Middle East security specialist at King's College London, sees it as a deliberate strategy of "territorial engineering." He argues that by creating a buffer between the official line and the physical barriers, "Israel preserves the ability to shift where Gazans may live, move and farm without ever formally announcing a change of border." But Efraim Inbar from the Jerusalem Institute for Strategy and Security suggests a more practical reason, speculating that IDF engineers might simply be placing the blocks where the terrain is most convenient.
These incursions involve more than just moving blocks. Video and satellite evidence show armored bulldozers and personnel carriers advancing as far as 400 meters beyond the designated line, often followed by the demolition of nearby buildings. In eastern Gaza City, hundreds of structures were demolished up to and even past where the blocks were first placed. Once the markers were shifted, the destruction only intensified. In Jabalia, for instance, a school complex located 150 meters inside the mapped line was completely razed. An IDF spokesperson defended the demolitions as necessary to dismantle Hamas's tunnel network, which they claimed could destabilize buildings on both sides of the line.
While the United States has said the second phase of the ceasefire is supposed to begin, there is still no timeline for another Israeli withdrawal. In the meantime, the concrete blocks continue to move, allowing Israel to carve out what Professor Krieg warns could become a "sterilised belt" from parts of Gaza.
"In practice," he concluded, "that means the status of land is less about what the ceasefire map says and more about where concrete blocks sit on a given day."
