Israel's Yellow Line advances deeper into Gaza, forcing families to flee again

Mahmoud Harzeen, 35, is pitching a tent about 200 metres from the yellow concrete blocks, preparing for his sixth move. Each time the line inches closer, he packs up his family of 10 and moves further back.

"Every time they move forward a little, we move back a little," he told Al Jazeera.

His most recent relocation barely lasted a night. After spending time setting up the tent, he slept in it once before Israeli forces moved the Yellow Line forward again.

"I pitched the tent and slept in it for one night," he said. "The next morning, we took our bedding and our things and left."

Harzeen can no longer recall the dates of each displacement. Instead he remembers the places, one after another: Zeitoun, Sahat al-Shawa, al-Muntazah. He described living amid drones, helicopters, artillery fire and stray bullets, with shrapnel posing a constant danger. The nights when the line advances are particularly frightening, he said, recalling tanks, troops and heavy shelling as the blocks were moved.

The Yellow Line divided Gaza's territory between Israeli and Palestinian control as part of the October 2025 ceasefire agreement. Israeli forces withdrew behind the line but have continued to move the demarcation deeper into Gaza. According to the United Nations, Israel now controls about 65 percent of Gaza, up from the 53 percent agreed a year ago.

With the latest advance, more of Shujayea has been brought under Israeli military control, and Israel's shifting boundaries continue to restrict where displaced families can live and move.

Analysis

Why This Matters

The territory available to displaced Palestinian families keeps shrinking as the Yellow Line moves westward, prolonging a year-long cycle of repeated flight.
UN figures show Israeli-controlled territory has grown from the 53 percent agreed under the ceasefire to about 65 percent of Gaza, well beyond the original demarcation.
Each advance is reported to be accompanied by tanks, shelling and displacement, indicating that the ceasefire has not ended instability for civilians near the line.

Background

The Yellow Line was drawn under the October 2025 ceasefire agreement, dividing Gaza between Israeli and Palestinian control, with Israeli forces withdrawing behind it. The agreement was meant to halt a war that had devastated the strip. In the year since, the line has repeatedly shifted deeper into Gaza, and displaced residents describe a pattern: the demarcation moves forward, families move back, and the cycle repeats. The UN has tracked the expansion of Israeli-controlled territory from the agreed 53 percent to roughly 65 percent, but the line's location is set on the ground by the movement of concrete blocks rather than by formal negotiation.

Key Perspectives

Displaced residents: Describe a relentless cycle of upheaval. Harzeen's experience of six moves in a year, including one shelter used for a single night, illustrates how the advancing line keeps families permanently unsettled and exposed to drones, shelling and shrapnel.

The United Nations: Its monitoring provides the benchmark for the line's expansion, reporting that Israeli control of Gaza has grown by about 12 percentage points beyond the level agreed when the ceasefire was signed.

Critics and observers: The continued westward movement of the line undercuts the ceasefire agreement's terms, and the reported shelling that accompanies each advance raises questions about whether the arrangement can provide the stability it promised.

What to Watch

Whether Israeli forces move the yellow concrete blocks further westward in Shujayea or other eastern neighbourhoods in the coming weeks.
Updated UN assessments of the share of Gaza under Israeli control and how far it rises above the current 65 percent.
Whether the ceasefire framework is renegotiated or formally revised as it approaches its one-year mark, given the line's steady expansion.
