Did an Israeli medical facility bust violation the rules of war?

.THE male in the wheelchair, driven along by 3 companions, seems like some other client in the Ibn Sina hospital in the West Banking company. Therefore does the lady in a headscarf apparently holding a little one. Others, in scrubs, seem like health care workers.

Yet seconds later on they pull out rifles and kill 3 Palestinians. Within ten minutes they are actually gone. Israel says it got rid of 3 revolutionaries in the course of the bust on January 30th and fended off a major attack which loomed.

However masquerading combatants as clinical employees possibly breaks worldwide law, which prohibits “perfidy”. What is actually that criminal activity?
