OSLO - A huge explosion damaged government buildings in central Oslo on Friday including Norwegian Prime Minister Jens Stoltenberg's office, injuring several people, a Reuters witness said.
The blast blew out most windows on the 17-story building housing Stoltenberg's office, as well as nearby ministries including the oil ministry, which was on fire.
Reuters correspondent Walter Gibbs said he counted at least eight injured people. The cause of the blast was unknown but the tangled wreckage of a car was outside one building. Police and fire officials declined comment on the cause.
