Iraqi Prime Minister Nouri al-Maliki announced the killings of Abu Omar al-Baghdadi and Abu Ayyub al-Masri at a news conference in Baghdad and showed reporters photographs of their corpses. "The attack was carried out by ground forces which surrounded the house, and also through the use of missiles," Maliki said. "During the operation computers were seized with e-mails and messages to the two biggest terrorists, Osama bin Laden and deputy Ayman al-Zawahiri," Maliki added. U.S. forces commander Gen. Raymond Odierno praised the operation. "The death of these terrorists is potentially the most significant blow to al-Qaeda in Iraq since the beginning of the insurgency," he said. "There is still work to do but this is a significant step forward in ridding Iraq of terrorists."
