The Israeli military is exerting control over more of Gaza than expected from the ceasefire deal with Hamas, a BBC Verify analysis has found.

Under the first stage of the deal, Israel agreed to retreat to a boundary running along the north, south and east of Gaza, marked by yellow blocks known as the Yellow Line. However, recent videos and satellite images show that these markers have been positioned hundreds of meters deeper into Gaza than specified in the ceasefire agreement.

Israeli Defence Minister Israel Katz instructed troops to place these markers, warning that anyone crossing them would be met with fire. There have already been deadly incidents reported near this newly defined boundary.

The Israel Defense Forces (IDF) did not comment on the allegations but stated that troops were establishing tactical clarity on the ground.

Analysis reveals uncertainty about the boundary's precise location, with various conflicting maps from different authorities creating confusion. Notably, drone footage has shown markers placed as much as 520 meters into Gaza, alongside heavy machinery in operation to establish this boundary.

In southern Gaza, satellite imagery shows markers erected as far as 290 meters inside the planned Yellow Line, suggesting that Israel may control more territory than anticipated. Analysts interpreting these reports suggest the blocks create a buffer zone, potentially allowing Israeli forces to engage targets before they reach operational bases, thereby enhancing security around IDF personnel.

Local residents express frustration and confusion, with reports indicating they lack a clear understanding of where it is safe to be. The situation is exacerbated by statements from Israeli officials that reinforce the danger posed by straying near these markers.

The overall legal status of such tactics is under scrutiny, with experts highlighting that international law mandates a responsibility to minimize civilian harm, even if individuals approach the newly placed boundaries as defined by the IDF.

This escalation follows a military campaign launched in response to the assault on October 7, resulting in significant casualties. The humanitarian toll continues as the situation in Gaza remains critical.
