Al-Douri, No. 6 on the list of Iraq's most wanted, is believed responsible for some of the 30 or more daily attacks on American forces in Iraq.
Aircraft bombed and destroyed one of his homes in Tikrit early Wednesday after officials determined insurgents were using it as an observation post.
The deputy director of coalition military operations, Brig. Gen. Mark Kimmitt, told reporters U.S. aircraft dropped two 2,000-pound bombs on buildings in Baqubah, north of Baghdad, and Navy jets bombed buildings in Tikrit Wednesday, continuing an aggressive offensive operation targeting suspected insurgents.
Kimmitt also announced artillery, mortars and firepower from attack helicopters and tanks -- along with 4th Infantry Division soldiers - Wednesday destroyed 12 enemy safe houses and buildings and suppressed 14 mortar-firing locations, as well as four ambush sites.
In addition to destroying the structures Kimmitt said more than 101 suspected enemy fighters were captured.
