The US command announced the arrest of an al-Qaida leader it said served as the link between the organization's command in Iraq and Osama bin Laden's inner circle, enabling it to wield considerable influence over the Iraqi group. The announcement was made Wednesday as the White House steps up efforts to link the war in Iraq to the September 11, 2001 terror attacks, with a growing number of Americans opposing the Iraq conflict. Some independent analysts question the extent of al-Qaida's role in Iraq. Khaled Abdul-Fattah Dawoud Mahmoud al-Mashhadani was the highest-ranking Iraqi in the al-Qaida in Iraq leadership when he was captured July 4 in Mosul, US military spokesman Brig. Gen. Kevin Bergner said. Bergner told reporters that al-Mashhadani carried messages from bin Laden, and his deputy Ayman al-Zawahri, to the Egyptian-born head of al-Qaida in Iraq, Abu Ayyub al-Masri.
