BAGHDAD - The U.S. command said Wednesday the highest-ranking Iraqi in the leadership of al-Qaida in Iraq has been arrested, adding that information from him indicates the group's foreign-based leadership wields considerable influence over the Iraqi chapter.

Khaled Abdul-Fattah Dawoud Mahmoud al-Mashhadani, also known as Abu Shahid, was captured in Mosul on July 4, said Brig. Gen. Kevin Bergner, a military spokesman.

"Al-Mashhadani is believed to be the most senior Iraqi in the al-Qaida in Iraq network," Bergner said. He said al-Mashhadani was a close associate of Abu Ayub al-Masri, the Egyptian-born head of al-Qaida in Iraq.

Bergner said al-Mashhadani served as an intermediary between al-Masri and Osama bin Laden and al-Qaida No. 2 Ayman al-Zawahri.

"In fact, communication between the senior al-Qaida leadership and al-Masri frequently went through al-Mashhadani," Bergner said.
