The NYTimes did a story providing good context:
Cases like Omran’s are a daily sight in eastern Aleppo, several doctors said, but he was lucky in that he made it to a hospital that was still open.
On Thursday morning, journalists from around the world were clamoring in an online chat group for more information about Omran and his family. But the doctors had moved on.
They were handling yet another influx from a bombing in the morning, later posting new images. A boy lay on the floor, his legs missing. A woman in black put her hand to her mouth in anguish.
Another boy lay on a gurney, soaked in blood, as a clinician worked on him. A few minutes later came another text message: The boy had died. His name was Ibrahim Hadiri, and there was a new photograph of his face, eyes closed. It is not likely to go viral.
