An open-source investigation into the bombing of four UNRWA schools sheltering displaced civilians in northern Gaza, within 72 hours in early November 2023.
This investigation geolocated four attacks on UNRWA-run schools in northern Gaza by matching visible landmarks in videos and photographs circulated on X (Twitter), Instagram, Telegram, Facebook and TikTok against satellite imagery and pre-war photographs of each school.
Chronolocation relied on shadow analysis using the SunCalc tool, cross-referenced against the timestamps of the first social media reports and officially released footage, to narrow down the likely time of each strike.
Damage patterns — crater shape, shrapnel dispersion and injury types — were compared against Amnesty International's documentation of munitions used in Gaza, to assess the likely type of ordnance involved in each attack.
Resolution 2601, United Nations Security Council 2021.
In the Gaza Strip, since the attacks began on October 7, 2023, schools and other educational facilities have been repurposed as shelters for displaced civilians seeking safety.

The smoke from the shelling made it challenging to determine the precise time of the attack through shadow analysis. However, based on the available data, it was estimated that the attack likely occurred between 7:54 a.m.—the time of the first news report—and 8:53 a.m., which is when a video documenting the attack was uploaded, as per Gaza local time.
