From CNN’s denial story:
“Raafat Hamdouna, administrative director at Shifa Hospital in Gaza City, said Friday that “Mahmoud Khalil Mashharawi, a 12-year-old, was brought to the hospital, and he was breathing, but he was hit in the head and all over his body by shrapnel. He died later in the hospital. He was treated by the Norwegian team. When he was brought in, he was breathing. The team did their best to save him. I am not really sure if they even tried to rush him to the surgery room, because he was badly hurt.”

The description is completely inconsistent with the images in the video.
