New York Times:

In the deadliest day in Baghdad since the latest American-led security plan for the city took effect two months ago, at least 171 people were killed today in a flurry of insurgent attacks, including car bombs that tore through predominantly Shiite crowds gathered at a bus hub, on a shopping street and near a police checkpoint, the authorities said.

In the worst of the attacks, a car packed with explosives exploded at an intersection in the Sadriya neighborhood that serves as a station for buses traveling to the Shiite district of Sadr City. The blast killed at least 140 people and wounded 150; incinerated dozens of vehicles, including several minibuses full of passengers; and charred nearby shops, witnesses and the police said.

As rescuers crowded the site, a sniper opened fire on the crowd, killing at least one more person and wounding two others.
