Three Years of War

Three years after U.S.-led troops invaded Iraq, the country is still struggling to find peace, repair war damage and form a permanent government. The insurgency, which includes loyalists of ousted president Saddam Hussein as well as foreign Islamic guerrillas, continues to claim thousands of Iraqi lives. More than 2,300 U.S. troops also have died. Following the recent bombing of a Shiite Muslim shrine, sectarian violence has flared, sometimes involving factional militias. The fledgling Iraqi security forces have been unable to stop the fighting.
