Senior U.S. defense and military officials say that Iraq's prime minister is asking the coalition for more police training, particularly for Sunnis who will have to secure Ramadi and other towns once Islamic State militants are ousted.

The prime minister made his request during talks with U.S. Defense Secretary Ash Carter this week at the World Economic Forum in Switzerland.

Coalition airstrikes aided Iraqi security forces in retaking Ramadi last month. Iraq's trained local police then moved in to secure the town. The U.S. officials say the local police were able to take over more quickly than initially anticipated, allowing more skilled Iraqi security and counterterrorism forces to move on to other operations.

The officials spoke on condition of anonymity because they weren't authorized to discuss the private conversation publicly.
