An explosion in Oslo, Norway early this morning, (early morning, California time; it was just after 3pm in Oslo), has now been officially confirmed to have been a bomb. At least two people are confirmed to have died, and thus far we have no idea about injuries
There is speculation as to the target; the blast did occur very close to the office of the Prime Minister, but so far no definite idea. Some have mentioned an Islamic activist who is being deported to Iraq. Some have mentioned the recent re-printing of "anti-Islamic" cartoons by a newspaper whose offices are nearby the blast. Others have pointed to Norway's participation in the NATO missions in Libya and Afghanistan. There is always the possibility of a false-flag attack by Mossad, in order to discredit Islam in general, prior to the expected UN showdown in September over a unilateral declaration of Palestinian statehood.
At this point, all we know for certain is that this is the ugliest thing to happen in Norway since World War II.
