It is possible that a terrorist attack was executed on government buildings in Oslo, Norway. While no cause has been confirmed yet, the wide spread damage and two distinct explosions (one near Prime Minister’s office and one near Parliament) suggest this was an attack. See a video of the Oslo Norway explosion scene below.
There are reports of two deaths so far in the blast.
A possible connection is the charges placed on Mullah Krekar, an Iraqi-born cleric and founder of Islamist Kurdish group Ansar Al Islam, who is currently living in Norway. He was charged with terrorism after warning authorities of eminent death if he was deported.
There have been other incidents, like political cartoons published in newspapers depicting the Muslim Prophet Muhammad in what some have called an offensive manner.
