4,000

MSNBC:

Four U.S. soldiers were killed by a bomb blast in southern Baghdad late Sunday, raising the death toll for American forces since start of the war to 4,000, according to the Pentagon.

The grim milestone was reached less than a week after the fifth anniversary of the U.S. invasion to topple former Iraqi dictator Saddam Hussein and coincided with a spate of violence across Iraq on Sunday that left at least 61 people dead.
