The U.S. military says at least 14 American soldiers were killed in Iraq in the first three days of June, including four in a single attack in Baghdad Sunday.
The military says six troops overall were killed Sunday in incidents in and around Baghdad. In each attack, the troops' vehicles struck roadside bombs or were hit by improvised explosive devices.
The military says eight U.S. troops were killed in incidents on Friday and Saturday.
This comes after 127 U.S. troops were killed in May, the third-deadliest month for U.S. forces since the invasion of Iraq in 2003.
In other violence Sunday, Iraqi police say a suicide car bomber killed 10 people, including a police officer, and wounded at least 25 others in an attack on a police convoy north of Baghdad.
Separately, Iraqi President Jalal Talabani said Sunday on ABC's "This Week" that U.S. troops will need to be in Iraq until the end of 2008.
U.S. Ambassador to Iraq Ryan Crocker told Fox News Sunday it is too soon to pass judgment on whether the U.S. troop surge in Iraq is a success. Democratic U.S. Congressman John Murtha of Pennsylvania, a vocal war critic, said the troop surge is not working.
