Did an Israeli healthcare facility bust violation the regulations of war?

.THE MAN in the wheelchair, pushed along by 3 friends, resembles some other patient in the Ibn Sina healthcare facility in the West Bank. So carries out the female in a headscarf obviously holding an infant. Others, in scrubs, resemble clinical personnel.

However minutes later they take out rifles and also get rid of three Palestinians. Within 10 minutes they are actually gone. Israel says it did away with 3 revolutionaries during the course of the raid on January 30th and warded off a major strike which loomed.

Yet masquerading fighters as clinical personnel possibly breaks international rule, which bans “perfidy”. What is actually that criminal offense?
