Didn't last long,
Well informed Iraqi sources in the Shiite holy cities of Najaf and Qom have revealed to Asharq Al-Awsat that the leader of the Sadrist movement, Moqtada al-Sadr, who returned to Iran after spending only two weeks in Iraq, left after receiving threats from the Asaib Ahl al-Haq group, and due to fears that the arrest warrant, issued against him against the backdrop of the assassination of Shiite cleric Abdul Majid al-Khoei in April 2003, would be enforced.
Informed sources in the Iraqi holy city of Najaf disclosed to Asharq Al-Awsat that "those observing what is happening did not expect al-Sadr to remain in the city of Najaf for long, because of rumours about serious threats being issued against him by the Asaib Ahl al-Haq group. The Asaib Ahl al-Haq group is said to have issued a statement declaring the killing of Moqtada al-Sadr lawful. This statement was then distributed to some residents of Najaf, who subsequently detailed its content to the leader of the Sadrist movement."
The Najaf source also revealed that "sources close to al-Sadr informed him of their fears that governmental parties - in a reference to Nouri al-Maliki - will try to exploit the arrest warrant issued against him by a Najaf investigative judge in late 2003...for al-Khoei's death."
