Iraqi Offensive Met by Wave of New Violence From Insurgents - New York Times

BAGHDAD, Iraq, May 29 - The largest Iraqi-led counterinsurgency operation since the downfall of Saddam Hussein set off a violent backlash on Sunday across Baghdad. At least 20 people were killed in the capital, 14 of them in a battle lasting several hours when insurgents initiated sustained attacks on several police stations and an army barracks.

The violence, including at least four suicide car bombings, was a bloody start to an operation that Iraq's new Shiite-majority government had presented as a new get-tough policy toward Sunni Arab insurgents, first in Baghdad and then countrywide. The government has said it will commit 40,000 uniformed Iraqis to the Baghdad operation in an effort to crush insurgents who reacted to the government's swearing-in four weeks ago with one of the war's biggest rebel surges."
