Six years after the intense fighting began in the Iraqi town of Fallujah between US forces and Sunni insurgents, there is a disturbingly large number of cases of birth defects in the town. Fallujah is less than 40 miles (65km) from Baghdad, but it can still be dangerous to get to. As a result, there has been no authoritative medical investigation, certainly by any Western team, into the allegations that the weapons used by the Americans are still causing serious problems. The Iraqi government line is that there are only one or two extra cases of birth defects per year in Fallujah, compared with the national average. But in the ... Fallujah General Hospital ... we found a paediatric specialist, Dr Samira al-Ani, who told us that she saw two or three new cases every day. Most of them, she said, exhibited cardiac problems. The specialist, like other medical staff at the hospital, seemed nervous about talking too openly about the problem. But it is impossible, as a visitor, not to be struck by the terrible number of cases of birth defects there. We heard many times that officials in Fallujah had warned women that they should not have children. We went to a clinic for the disabled, and were given details of dozens upon dozens of cases of children with serious birth defects.
