Palestinian health authorities in Hamas-controlled Gaza said Israel struck a convoy of ambulances on Friday that was to leave al-Shifa Hospital in Gaza City and head to the south of the enclave to evacuate injured people.
Israel is not aiming to maintain the situation because that was what they were doing before. Their goal is to win the war and completely eradicate Hamas as a power structure. Everything is to further that end within international law.
Hamas is doing their best to embed themselves within restricted targets and Israel does not always have the ability to tell when a building or vehicle they are seen going into is a restricted target. That does not make it illegal. It is also a war crime by Hamas. It places the blame purely on the side with knowledge of the ground. I'm yet to see Hamas get blamed for this in this conflict yet it absolutely is on them.
