Iraqi officials say a car bomb has killed 10 people and injured more than 20 in a town northeast of Baghdad.
Authorities immediately imposed a curfew in the town of Khalis, in Diyala Province.
Police said the car bomb exploded in a marketplace as shoppers were starting to arrive.
The blast underscored Iraq's fragile security as the remaining 13,000 U.S. troops pull out in the next few weeks, nearly nine years after the invasion that ousted Saddam Hussein.
