Did an Israeli medical facility bust breach the laws of war?

.THE male in the wheelchair, driven along by three companions, seems like any other patient in the Ibn Sina health center in the West Bank. Therefore does the female in a headscarf apparently holding an infant. Others, in scrubs, appear like clinical personnel.

However minutes later they pull out rifles as well as eliminate 3 Palestinians. Within 10 minutes they are gone. Israel says it dealt with three terrorists during the course of the raid on January 30th and also fended off a major attack which loomed.

But disguising fighters as medical staffs possibly breaks worldwide legislation, which restricts “perfidy”. What is that criminal offense?
