In Iraq, residents of the Sadr City district of Baghdad say they’re being warned to flee their homes in advance of an intensified US-led assault on Shia fighters. Sadr City has seen relentless violence in a nearly two-month campaign against followers of Muqtada al-Sadr. UNICEF says around 6,000 people have already been forced to flee. Up to 150,000, half of them children, are said to be cut off from aid in areas isolated by the US military. Medical care has declined following Saturday’s US missile strike that damaged several ambulances at Sadr City’s main hospital. At least four people were killed and thirteen injured in fighting overnight. At the White House, the veteran correspondent Helen Thomas questioned Press Secretary Dana Perino about the killing of innocent Iraqis.

Dana Perino: “Helen.”

Helen Thomas: “Yesterday, according to the New York Times, we dropped a bomb on a home in Sadr City and burned alive a pregnant woman and her children. How long is the siege of Sadr — how long are we going to keep bombing Iraqis?”

Perino: “Well, I’m not aware of that particular report. I have not — I’ve not seen it.”

Thomas: “Well, it was pretty buried in the stories.”

Perino: “OK. Well, the operation against the militias in Sadr City will continue until they root them out. And that is expressly in order to protect people like you just mentioned.”

Thomas: “Root who out? The Iraqis? In their own country?”

Perino: “It is Prime Minister Maliki’s government which is going after the militia, which is appropriate.”

Thomas: “Why are we bombing these people?”

Perino: “Any time anyone that is an innocent civilian is hurt in a conflict, we obviously regret it, and we go out of our way to make sure it doesn’t happen.”
