I've seen some pictures that the rockets were launched from what seemed to be the east of Rafah close to the border but no videos that they were launched from this tent camp. This tent camp was in the west of Rafah.
Brix camp to the west of the city of Rafah.
The previous attack from Hamas on israels military base next to the Ker Shalom crossing was launched more than 350 meters away from the nearest civilian area, Which is pretty impressive considering how densely populated Rafah is.
I might have missed some footage though, if you have additional footage feel free to link it.
