U.S. death toll in Iraq reaches 2,500

The number of U.S. military deaths in the Iraq war has reached 2,500, the Pentagon said Thursday, more than three years into a conflict that finds U.S. and allied foreign forces locked in a struggle with a resilient insurgency.

In addition, the Pentagon said 18,490 U.S. troops have been wounded in the war, which began in March 2003 with a U.S.-led invasion to topple President Saddam Hussein.

Tens of thousands of Iraqis have been killed.

This is a developing story and details will be added as they become available.
