Did an Israeli health center bust violation the rules of battle?

.THE guy in the wheelchair, driven along through 3 companions, looks like some other person in the Ibn Sina medical center in the West Bank. Therefore carries out the woman in a headscarf seemingly carrying a little one. Others, in scrubs, resemble clinical staff.

But seconds eventually they pull out rifles as well as eliminate 3 Palestinians. Within 10 mins they are gone. Israel states it eliminated 3 terrorists in the course of the bust on January 30th as well as avoided a major attack which was imminent.

Yet masquerading combatants as clinical personnel most likely ruptures worldwide regulation, which forbids “perfidy”. What is actually that unlawful act?
