Eyewitness video of explosion near PM's office in Oslo
A loud explosion shattered windows Friday at the government headquarters in Oslo which includes the prime minister's office, injuring several people. The blast comes as the Scandinavian country has grappled with a series of home-grown terror plots linked to al-Qaida, and six years after an uproar over cartoons of the Prophet Muhammad in neighbouring Denmark.
