The White House offered condolences for the terrorist bombings that killed more than 70 people in Baghdad on Thursday, dpa reported.
"We strongly condemn the terrorist attacks against innocent Iraqis, which serve no agenda other than murder and hatred," Jay Carney, spokesman for President Barack Obama, said in a statement.
The attacks came days after the last US troops left Iraq, following the 2003 invasion that toppled the regime of Saddam Hussein.
Carney said that the bombings were an attempt "to derail Iraq's continued progress," but would not succeed.
"Iraq has suffered heinous attacks like this in the past, and its security forces have shown they are up to the task of responding and maintaining stability," he said.
"Time and again, the Iraqi people have shown their resilience in overcoming efforts to divide them. We continue to urge leaders to come together to face common challenges."
Carney said that Vice President Joseph Biden had spoken Thursday with Iraqi President Jalal Talabani to offer "our full support."
