Did an Israeli healthcare facility raid violation the rules of battle?

.THE guy in the mobility device, pushed along through 3 friends, seems like some other person in the Ibn Sina health center in the West Banking company. Thus performs the female in a headscarf evidently bring a baby. Others, in scrubs, look like clinical team.

Yet minutes later they take out rifles and kill three Palestinians. Within 10 minutes they are actually gone. Israel claims it removed three terrorists during the raid on January 30th and warded off a significant assault which was imminent.

Yet masquerading fighters as clinical personnel perhaps breaks international regulation, which prohibits “perfidy”. What is actually that unlawful act?
