Did an Israeli medical center bust violation the regulations of battle?

.THE MAN in the wheelchair, driven along by three partners, seems like any other client in the Ibn Sina healthcare facility in the West Bank. So performs the female in a headscarf apparently holding a little one. Others, in scrubs, resemble health care personnel.

Yet instants later they take out rifles as well as kill 3 Palestinians. Within ten moments they are actually gone. Israel claims it did away with three revolutionaries during the course of the bust on January 30th and warded off a significant assault which impended.

But masquerading combatants as health care employees probably breaks worldwide regulation, which forbids “perfidy”. What is actually that criminal offense?
