The latest operation follows August's Operation Lightning Hammer that focused on al Qaeda’s presence in the Diyala River Valley north of the provincial capital Baqubah. Baqubah itself was cleared of al Qaeda during Operation Arrowhead Ripper, which was launched in June. The Baghdad Security Plan and Phantom Thunder and Phantom Strike operations -- which focused on al Qaeda and the Shia extremist cells in the Baghdad Belts -- have pushed al Qaeda operations into regions in Ninewa, Kirkuk, Salahadin, and Diyala provinces. This rolling series of operations is designed to keep al Qaeda off balance, prevent the terrorists from reorganizing safe havens in new regions, and expanding the security perimeter beyond Baghdad.
