Four U.S. soldiers died Monday from wounds suffered in a combat explosion in restive Diyala province north of Baghdad, the American military reported. Twelve others had minor injuries and returned to duty.

The military statement announcing the deaths gave no other details and said identities of the victims were withheld until family could be notified.
