The word “Hamas” is overlaid on the clip, which starts with a man dressed in a black T-shirt and denim shorts walking through a tunnel system.
The video includes the sounds of war, including a helicopter, gunfire, explosions and a cry of “Allahu Akbar” (Allah is the greatest).
The word “Kinemaster” is also overlaid on the video. Kinemaster is video editing software for gamers. Someone who looks to be a gamer appears in a smaller frame in the top left corner of the video at the 20 sec mark.
AAP FactCheck conducted a Google image search of a still from the video and sourced it to the TikTok account @urbexkev.
Urbex is a recreational pastime in which people explore derelict urban structures.
Many of the videos on the TikTok account are of underground bunkers, bomb shelters and old railway tunnels throughout England.
The Facebook clip is taken from a 10min video on the @urbexkev account which shows the same urban explorer in the black T-shirt. That video is tagged #bunker #war #ww2 #history #underground.
There’s no indication where the video was taken, but a clue is at the 2min 37sec mark, and the image of an old newspaper.
The word “Shelters” can be seen in the headline, above a photo of a man in a helmet. The page is torn across the lower half of the photo.
The same newspaper clipping can be seen in this image.
Several pictures show scenes also in the @urbexkev TikTok video.
This image, for example, showing a section of pipe and rubble, matches the TikTok video at the 1min 22sec mark, while this image showing an old section of ventilation pipe is seen at the 1min 34sec mark.
And this image, showing where the old newspapers were discovered, matches the TikTok video from the 2min 12sec mark.
The same tunnel system, including the old newspapers, piping and rubble, are seen in a YouTube video from a different “urbex” team.
The description names the tunnels “Reigate Battle HQ”, or “Reigate Citadel”, and says it is a military structure which played a significant role during WWII.
The claim a Facebook video shows a Hamas tunnel system beneath Gaza is false.
The video has been misrepresented. The original clip features urban explorers walking through a World War II tunnel system in southern England.
False — The claim is inaccurate.
