War Crimes

Excerpted from an article in the New Standard:

"Nov 9 - In a series of actions over the weekend, the United States military and Iraqi government destroyed a civilian hospital in a massive air raid, captured the main hospital and prohibited the use of ambulances in the besieged city of Fallujah."

How in the universe is this not a violation of the Geneva Convention? Geneva Convention Chapter III Article 19 clearly states:

"Art. 19. Fixed establishments and mobile medical units of the Medical Service may in no circumstances be attacked, but shall at all times be respected and protected by the Parties to the conflict. Should they fall into the hands of the adverse Party, their personnel shall be free to pursue their duties, as long as the capturing Power has not itself ensured the necessary care of the wounded and sick found in such establishments and units.

The responsible authorities shall ensure that the said medical establishments and units are, as far as possible, situated in such a manner that attacks against military objectives cannot imperil their safety."

Now our troops are capturing hospitals and prohibiting them from using their ambulances to do their jobs and save lives. Aside from the fact that it's criminal, could someone please explain to me how keeping the sick and injured from receiving medical treatment is actually helping the Iraqis? We claim we're there to free them and help them--this is not helping.
