The US army does not count the number of Iraqis killed since the invasion in March 2003. The most conservative figure for the number dead is 10,000 as calculated by private groups. It is rising every day. The US military claimed that on Tuesday alone it killed "100 militants" in air strikes on Fallujah on top of a further 33 people killed in fighting in Sadr City in Baghdad. Donald Rumsfeld, the US Defence Secretary, proudly claimed on Tuesday that US forces had, last month, killed between 1,500 and 2,500 Iraqi insurgents. He did not note an ominous trend that, for the first time, more Americans were probably killed by Shia fighters than by Sunni guerrillas. For the US, it is now a war on two fronts.
