From a Reuters report:
SNIP
Residents in the city said a U.S. air strike had destroyed a clinic that had been receiving casualties after U.S. and Iraqi forces seized the main hospital on Monday night.
Some medical staff and patients had been killed at the one-story Popular Clinic in a central district, they added.
Sami al-Jumaili, a doctor at the main Falluja hospital who escaped arrest when it was taken, said the city was running out of medical supplies and only a few clinics remained open.
"There is not a single surgeon in Falluja. We had one ambulance hit by U.S. fire and a doctor wounded. There are scores of injured civilians in their homes whom we can't move.
"A 13-year-old child just died in my hands," he said by telephone from a house where he had gone to help the wounded.
Doctors said at least 15 civilians had been killed in Monday's fighting. There was no word on U.S. casualties.
