Here are excerpts just released from the cablegate (wikileaks) trove of top secret US cables (this one was sent to Condoleeza Rice, then Secretary of State). Please read them and judge for yourself. (the original cable is here)
[…] American troops approached Mr. Faiz’s home in the early hours of 15 March 2006. It would appear that when the MNF approached the house, shots were fired from it and a confrontation ensued for some 25 minutes. The [US] troops entered the house, handcuffed all residents and executed all of them. After the initial [Multinational Forces] intervention, a US air raid ensued that destroyed the house [thereby destroying all evidence there].
Iraqi TV stations broadcast from the scene and showed bodies of the victims (i.e. five children and four women) in the morgue of Tikrit. Autopsies carries out at the Tikrit Hospital’s morgue revealed that all corpses were shot in the head and handcuffed. […]
[A]t least 10 persons, namely Mr. Faiz Hratt Khalaf, (aged 28), his wife Sumay’ya Abdul Razzaq Khuther (aged 24), their three children Hawra’a (aged 5)Aisha ( aged 3) and Husam (5 months old), Faiz’s mother Ms. Turkiya Majeed Ali (aged 74), Faiz’s sister (name unknown), Faiz’s nieces Asma’a Yousif Ma’arouf (aged 5 years old), and Usama Yousif Ma’arouf (aged 3 years), and a visiting relative Ms. Iqtisad Hameed Mehdi (aged 23) were killed during the raid.
