.THE MAN in the wheelchair, pressed along by three companions, appears like every other person in the Ibn Sina hospital in the West Bank. Thus does the female in a headscarf apparently carrying a child. Others, in scrubs, appear like health care workers. However minutes later they take out rifles and get rid of three Palestinians. Within 10 minutes they are gone. Israel mentions it removed 3 terrorists in the course of the bust on January 30th as well as warded off a major assault which impended. However disguising fighters as health care staffs probably ruptures international regulation, which restricts "perfidy". What is actually that unlawful act?
