There has been an explosion in Oslo near the office of Norwegian Prime Minister Jens Stoltenberg. While Stoltenberg was not harmed and no fatalities have been reported there are reportedly dozens of people who have injured. Several government buildings were damaged along with the offices of Verdens Gang, a Norwegian tabloid.

As of this writing, Norwegian authorities have not commented what caused the explosion. At this point, no one has claimed responsibility for it although one certainly cannot discount the possibility of Islamic terrorism. Like most European countries, Norway has had its share of troubles in absorbing Muslim immigrants. Even some Norwegian leftists have called for Norway to adopt a more restrictive immigration policy. And like in other parts of the EU, there has been also been a disturbing resurgence of anti-Semitism in Norway.

UPDATE: I see that John Tabin beat me to the punch and I am glad he did. I was not aware that Mullah Krekar had been indicted last week. Krekar is mentioned prominently in the Jerusalem Post piece on Norwegian anti-Semitism to which I linked.

UPDATE II: The Los Angeles Times is reporting that at least two people have been killed in the explosion.

UPDATE III: The Jerusalem Post and Reuters report that seven have been killed in the bomb blast in Oslo. It is also believed there have been several fatalities at the Norway Labour Party Youth retreat and that there may be explosives in the camp.

UPDATE IV: The New York Times reports that a group called Ansar al-Jihad al-Alami has claimed responsibility for the attack citing Norway’s presence in Afghanistan and “unspecified insults to the Prophet Muhammad” although this has not been independently confirmed.
