If you watch the video above you'll see how the crew identifies a mosque, to NOT fire on it. I don't believe for a second that that the US would deliberately sustain fire on a hospital. I do believe this is an accident. The question is, how did it happen. We can only speculate here, we weren't there, and maybe we shouldn't speculate but it's a rumor forum. To me, the most likely speculation is that the crew didn't have the information that it's a hospital.
