Aswat al-Iraq: Iraqi army on Thursday announced its troops arrested three al-Qaeda-linked group gunmen in a military operation conducted in Ninewa. "An Iraqi army force captured a gunman from self-proclaimed Iraq's Islamic State during a security operation conducted in Eden district, east Mosul," a Ninewa military source told Aswat al-Iraq. "The force captured two more gunmen after tips confessed by the first detainee," the source noted. Self-proclaimed Iraq's Islamic State is a mantle for a number of Sunni groups. Al-Qaeda network in Iraq is one of major founders.
