Iraq implodes as Shia fights Shia

Another tragedy as the Shia majority turn on each other

A new civil war is threatening to explode in Iraq as American-backed Iraqi government forces fight Shia militiamen for control of Basra and parts of Baghdad.

Heavy fighting engulfed Iraq's two largest cities and spread to other towns yesterday as the Iraqi Prime Minister, Nouri al-Maliki, gave fighters of the Mehdi Army, led by the radical cleric Muqtada al-Sadr, 72 hours to surrender their weapons.

The gun battles between soldiers and militiamen, who are all Shia Muslims, show that Iraq's majority Shia community – which replaced Saddam Hussein's Sunni regime – is splitting apart for the first time.

Mr Sadr's followers believe the government is trying to eliminate them before elections in southern Iraq later this year, which they are expected to win.

Mortars and rockets launched from Mehdi Army-controlled districts of Baghdad struck the Green Zone, the seat of American power in Iraq, for the third day yesterday, seriously wounding three Americans. Two rockets hit the parking lot of the Iraqi cabinet. The mixed area of al-Mansur in west Baghdad, where shops had begun to reopen in recent months, was deserted yesterday as Mehdi Army fighters were rumoured among local people to be moving in from the nearby Shia stronghold of Washash. "We expect an attack by the Shia in spite of the Americans being spread over Sunni districts to defend them," said a Sunni resident.

Forty people have been killed and at least 200 injured in Basra in the last two days of violence. In the town of Hilla, south of Baghdad, 11 people were killed and 18 injured yesterday by a US air strike called in support of Iraqi forces following street battles with Shia militia members in the city's Thawra neighbourhood. In Baghdad, 14 have been killed and 140 wounded. Independant
