Oslo bomb was "Oklahoma City-type": Police

A police official has told The Associated Press that the bomb used in the attack at the Norwegian prime minister's office was "some kind of Oklahoma City-type" device made of fertilizer and diesel fuel.

The official said it remains unclear what kind of detonator was used for the bomb, which investigators say was packed into a panel truck and killed at least seven people when it went off.

The official was speaking on condition of anonymity because the information has not been formally released.

A 4,000 pound fertilizer-and-fuel-oil bomb detonated in front of a federal building in Oklahoma City in 1995, killing 168 people.
