More US servicemen have died since the start of the US-led war to topple former president Saddam Hussein's regime than died in the first three years of conflict in Vietnam, according to analysis of US State Department figures. Figures indicate that 392 US servicemen were killed in conflict in Vietnam in 1962-1964. In comparison, the latest death in Iraq - caused by a roadside bomb in Baghdad - brought to 397 the number of US soldiers killed in Iraq since the start of the war.
