Shiite militiamen kill 25 Sunni Arabs in revenge attacks in Baghdad

BAGHDAD, Iraq — Shiite militiamen doused six Sunni Arabs with kerosene and burned them alive as Iraqi soldiers stood by, and killed 19 other Sunnis in attacks on their mosques Friday, taking revenge for the slaughter of at least 215 Shiites in the Sadr City slum the day before.

The mosque attacks came after the government, in a desperate attempt to avert civil war, imposed a sweeping curfew on the capital, shut down the international airport and closed the country's main outlet to the shipping lanes in the Persian Gulf.

The Mahdi Army militiamen, armed with machines guns and rocket-propelled grenades, swept through Hurriyah neighborhood near an Iraqi army post, burning four mosques and several homes, and attacking worshippers as they left Friday services, said police Capt. Jamil Hussein. Gunmen loyal to the radical anti-American Shiite cleric Muqtada al-Sadr had begun to take over the mixed neighborhood this summer and a majority of its Sunni residents had fled.

Three Sunni mosques elsewhere in Baghdad came under attack later in the day, and in Sadr City a U.S. helicopter shot back at Shiite militiamen who opened fire on it from the ground, residents said. There were no immediate reports of casualties.

Hussein said at least 25 Sunnis were killed and 14 wounded in the mosque attacks in Hurriyah, despite a 24-hour curfew that the government imposed to try to prevent reprisal killings in the capital.

The Baghdad attacks appeared to have been a reaction to the deaths in Sadr City on Thursday, when Sunnis unleashed bombs and mortars that killed 215 people and wounded 257 in the deadliest assault since the U.S.-led invasion. The killings threatened to tip Iraq's widespread sectarian violence into full-scale civil war pitting majority Shiites against minority Sunnis.

In the northern Iraqi city of Tal Afar, 23 people were killed and 43 wounded when explosives hidden in a parked car and in a suicide belt worn by a pedestrian detonated simultaneously outside a car dealership, said police Brig. Khalaf al-Jubouri.

In Baghdad, al-Sadr followers warned they would suspend their membership in parliament and the Cabinet if Prime Minister Nouri al-Maliki meets with President Bush in Jordan next week, a member of parliament said. Bush and al-Maliki were scheduled to meet Wednesday and Thursday in Amman.

The al-Sadr bloc in parliament and government is the backbone of al-Maliki's political support, and its withdrawal, if only temporarily, would be a severe blow to the prime minister's already shaky hold on power.
