I know of a hospital in Fallujah (referred to as the 'main', or 'big' hospital)being SEIZED, but not flattened. And YES, it was specifically seized to prevent it from being al Jazeera's lead story for the duration of the campaign, with no input from the Coalition about the truth of the stories coming out of it. Furthermore, we KNEW fighters would be brought in there, no matter if we were there or not, and what a great way to keep them from getting patched up and whisked off to sanctuary in Syria/Iran/wherever, or returning to the battle.
We seized it, helped it, stocked it, and even staffed it, but we didn't 'flatten' it, and I doubt we ever would, even if we were allowed to by the Law of Armed Conflict - which explicitly states when such structures lose their protected status.
It was a brilliant move, too. It netted enemy personnel, kept a vital asset out of their hands, kept it available for civil use, and made certain that al J couldn't tell one-sided lies about what was going on there. VERY successful.
