Iraqi and US forces arrested on Friday four suspected senior members of al-Qaeda during an air attack in the north-east province of Diyala, according to a security source, DPA reported.
Two of the men were arrested when a force from the Quick Response Department in Diyala province waged a joint air attack with US troops, targeting an al-Qaeda stronghold in the Hamrien mountains in Khanaqin, Naif al-Tamimi, of the department, told the German Press Agency dpa.
"In another air attack operation, forces arrested two other leaders in al-Mafraq neighborhood in central Baaquba," he added.
Several of the group's senior leaders have been arrested or killed over the past few months, as Iraqi and US forces launched a major offensive against al-Qaeda suspects throughout the country.
Deadly attacks that left dozens of Iraqis killed in the past weeks have been described as acts of revenge by al-Qaeda.
