It appears to be an inside job.
Turns out, al-Nuri had written a letter. He gave one copy to Sadr and another copy to a member of his family. Afterwhich, he said the following:
"I have done what I could but I know they will kill me."Eye Raki:
Many accuse elements in the Mehdi Army who wanted to silence the "moderate" Al-Noori because he wished to see Sadr's military wing disbanded. Today an extremely damaging letter, that was written and signed by Al-Noori himself and dated just over a week before he was killed, has been circulating on the internet in which he attacks the Mehdi Army has shed more light on this issue.Abbas at Catharis, a translation:
The letter, which is addressed to Moqtada, speaks of the "dangerous and uncomfortable" times the Sadr Movement is going through that can be exploited by "enemies". He advices Moqtada that "strong and quick" decisions need to made to "protect" the Sadr Movement.
To the Eminence of Sayyid Muqtada al-Sadr, Long be your glory.
May God's peace, mercy and blessings be upon you.
Praise be to Allah, the Mightiest Lord, and peace and blessings be upon my master and leader, the Prophet of Allah and his progeny, and peace be upon the martyr of the nation, the Holy Leader(=Sadr II, Qaddo's dad) (God Protects His Secret)
It is certain that your Eminence realize the difficult and critical circumstances the Mujahid Sadrist Trend is going through for various reasons and factors that could perhaps pose an opportunity for the enemies of this honorable trend, and for those seeking to eliminate it and weaken it.
Hereby, we think that to make those miss their opportunity and to protect this entity founded by the Holy Leader to defend the domain of Islam requires steadfast and quick decisions drawing from past experiences, I have mentioned in more than one occasion the mistakes and violations of some elements of the Imam Mahdi (may Allah hasten his reappearance) Army which gave the agents of the occupation a pretext to distort our reputation and denounce us.
Those corrupt elements which infiltrated the Army of Imam Mahdi (A.H.R.) have found itself a position to administer [incorrect spelling] army legions under various titles, they have carried out kidnapping, robbery and murder operations which negatively affected the populist image of the trend of the Holy Leader and its goals...thus, we see that you take into consideration the following matters so as to preserve the righteous path of the Mujahid Sadrist Trend:
1. The need to quicken the cleansing of the Sadrist Trend from corrupt elements which are commiting crimes under the protection of the Sadrist Trend and the Army of Imam Mahdi (AHR)
2. Internal, regional and international pressures force us to seriously consider the dissolution of the Army of Imam Mahdi (AHR), the recent events in Basrah and other governoates have brought undesirable effects on our popular base and so we believe that you take the incentive to dissolve the army quickly so as to preserve the eternal legacy left behind by the Holy Leader (God bless his secret)
and the final say goes to you in all that we have suggested
and may Allah's peace, mercy and blessings be upon you.

So, all of the propaganda about the "occupiers" taking him out, may be just that. Hey, if they want to take each other out, they have my blessing. Saves our bullets, bombs and men for the rest of the riff-raff.
