It is normal practice when detaining terrorist suspects to remove most of their clothing, to ensure they aren't concealing a bomb or other weapons. Just as Israel did it in the Gaza strip, the UK did it this morning in Fairford.
In 2023, just two months after the brutal Palestinian invasion of Israel, the BBC reported this arrest footage as "savage images, evoking humanity's darkest times". I wonder if they will do the same now for Fairford.
