That's a lot of bunk, Setanta.
One Iraqi Shi'a religious family which opposed working with the US-led occupation [and trying to get control from the al-Hakim family] is the al-Sadr family, which calls itself "The Active Religious Seminary". Until recently it was headed by Grand Ayatollah Muhammad Sadiq al-Sadr, who was assassinated along with two of his sons by presumed agents of Hussein in Al-Najaf in 1999.
The loyalty of many of his supporters passed to another son, Hojatoleslam Muqtada al-Sadr, a mid-level cleric about 30 years of age. Unlike his father, Muqtada had little formal religious standing to interpret the Koran, and relied for religious authority on an Iran-based Iraqi exiled cleric, Ayatollah Kazem al-Haeri, who was a student of Bakir al-Sadr. The militia wing of this movement was known as the "Mahdi Army" and was estimated as of early 2004 to consist of about 500-1000 trained combatants along with another 5,000-6,000 active participants. According to another US DOD estimate, the Mahdi Army was a group of about 3,000 lightly armed devotees of Sadr before operations against the group started. It was a small group on the margins, and while it wass unknown how large the group is, it had been degraded.
On June 4, 2004 Radio Free Europe/Radio Liberty reported that the Al-Mahdi Army consisted of 6,000 to 10,000 combatants.
Some younger Shiites have contended for power with the more traditional Shiite Muslims in the city and region. Sheik Muqtada al-Sadr and his young followers have sought to replace more traditional factions as the voice of Iraq's Shiite majority. The al-Sadr family portrays themselves as the ones doing the most to redress decades of suppression by Sunni Muslims under the Saddam's rule.
The al-Sadr group has drawn charges of involvement in attacks and intimidation in Al-Najaf that have highlighted political differences among Shi'a political organizations. The most notable of those attacks was a mob killing of a pro-US cleric, Abd al-Majid al-Khoi, shortly after his return from exile in London in early April. Al-Khoi was himself the son of another extremely powerful former grand ayatollah, Abolqassem al-Khoi. Al-Khoi was murdered as he emerged from the city's Imam Ali Mosque in a gesture of reconciliation with the mosque's custodian, who was popularly considered to have collaborated with Hussein's regime. The custodian was killed along with al-Khoi and it is unclear whether al-Khoi was an assassination target or was struck down because he tried to defend the other man.
Immediately after al-Khoi's murder, supporters of al-Sadr surrounded the house of another grand ayatollah in Al-Najaf, Ali Sistani, in what was taken to be a gesture of intimidation. Sistani -- who has said that Shi'a leaders should limit themselves to religious questions and stay out of politics -- went into hiding and only re-emerged after tribesmen loyal to him raced to Al-Najaf.
Al-Sadr's group denied it had anything to do with the April 2003 attempt on the elder al-Hakim, and said Hussein loyalists were to blame. But in 2004 an Iraqi judge issued an arrest warrant for al-Sadr in connection with the killing of Ayatollah Abd al-Majid al-Khoi in 2003.
Mustafa Al-Yaqubi was detained on April 3, 2004 in connection with the April 2003 murder of Ayatollah Sayyed Abdul Majeed al-Khoei. An Iraqi judge issued a warrant for Mr. Yaqubi's arrest as a result of an Iraqi criminal investigation and indictment. He was taken into custody at his home in An Najaf.
In early April 2004 the militia of Muqtada Al Sadr's army -- Jaysh Mahdi or Mahdi Army -- attempted to interfere with security in Baghdad, intimidate Iraqi citizens and place them in danger. The militia attempted to occupy and gain control of police stations and government buildings. During this attack, this illegal militia engaged coalition forces and ISF with small arms fire and RPGs. Coalition forces and Iraqi security forces prevented this effort and reestablished security in Baghdad. Coalition troops fought gun battles with members of Muqtada al-Sadr's Imam Al-Mahdi Army militia in the southern cities of Al-Nassiriyah, Amara, and Kut. Clashes etween al-Sadr's Al-Mahdi Army and coalition troops south of Baghdad tested the resolve of the United States' partners in Iraq.
By 07 April 2004 US-led coalition forces were involved in the most widespread fighting in Iraq since the fall of Saddam Hussein a year ago. Troops battled Shiite militias in half a dozen Iraqi towns and cities from near Kirkuk in the north to Basra in the south.
As of 08 April 2004 the Al-Mahdi Army had taken full control of the city of Al-Kut and partial control of Al-Najaf. Residents of Al-Kufah said militiamen had some control of that city as well. In Karbala, Polish and Bulgarian troops fought Al-Mahdi Army militants as hundreds of thousands of Shi'ites were gathering ahead of a religious festival. The Polish Army said commanders were meeting with moderate Shi'ite clerics after radicals demanded the withdrawal of coalition forces.
Hundreds of loyalists to radical Shi'ite cleric Moqtada al-Sadr attacked British troops Saturday 08 May 2004 in the center of Basra, south of Baghdad. They also assaulted the governor's offices there, and fired rocket-propelled grenades at the coalition headquarters. The British sent in reinforcements, tanks and armored vehicles to secure the area. Several Iraqi insurgents were killed in the gun battles. The violence erupted a day after a cleric in Basra told worshippers he would offer cash rewards for the killing or capture of British and American troops. He also said anyone who captured female soldiers could keep them as slaves. The cleric, Sheikh Abdul-Sattar al-Bahadli, said his offer was in response to the abuse of Iraqi prisoners by US soldiers. Al-Bahadli is the Basra representative of hard- line Shiite leader Muqtada al- Sadr.
The first week of August 2004 witnessed a cycle of growing violence which culminated with fierce clashes across central and southern Iraq between the Al-Mahdi Army and US, British, and Italian forces. It was the heaviest fighting since al-Sadr's forces agreed to a truce in June. In the southern city of Al-Nasiriyah, Iraqi fighters attacked Italian patrols with rocket-propelled grenades and gunfire. At least 20 Iraqis and one US soldier were reported killed on 5 August in Baghdad, Al-Najaf, and Al-Basrah. Militants brought down a US helicopter in Al-Najaf, though the US military recovered the crew unharmed. Al-Sadr offered to join a new reciprocal ceasefire, but it was unclear whether the fighting was a brief flare-up or the collapse of the truce.
