The IDF claims that, between their first video through the MRI room and when they led the BBC through it, they found another gun and put it in the MRI room.
We can take a step back and ask why guns made of metal were anywhere near an MRI, but we can also ask where the IDF supposedly “found” the original guns.
Also of note is that the laptop shown at the end of the “uncut” al-Shifa video… Uses an Israeli power plug and displays an IDF soldier. The IDF later took the video down and re-uploaded it with that picture blurred.
