Nine people were detained Saturday in Iraq in the kidnapping of three U.S. soldiers, UPI reported. The nine were detained when U.S.-led coalition forces raided a building near Fallujah. It was no immediately known what role the nine men may have played in the kidnappings more than a week ago, CNN reported. Military personnel said they have been working around-the-clock and using all available assets to find the three soldiers, who were kidnapped May 12 in predawn raid outside Mahmoudiya, in an area known as the Triangle of Death. Four U.S. soldiers and an Iraqi soldier died in the attack. Eleven men were detained earlier this week for the attack, CNN reported. Two of the men told interrogators they were paid by a middleman to take part in the raid, CNN reported. The Islamic State of Iraq, a Sunni insurgent group that includes al-Qaida in Iraq, has claimed responsibility for the attack. The U.S. military is offering $200,000 in reward money for information regarding the soldiers, CNN reported.
