Among those taken into custody Monday was a man who intelligence reports suggest oversaw the movement of bomb-making materials into Mosul, officials said. Eleven other suspects also were detained, American Forces Press Service said.
Also among those detained was a man and four associates believed to have connections to al-Qaida in Iraq, officials said. Troops discovered multiple rifles, munitions and bomb-making materials at the site.
Others were arrested Monday in Amariyah, Mosul, Beiji and Baghdad, where a cache of weapons was found.
Coalition and Iraqi forces reported detaining three suspected terrorists and capturing munitions and explosives in the Baghdad area Saturday.
