There has just been a pair of explosions in government buildings in Oslo, Norway; one near the Prime Minister's office and one nearby Parliament. Windows in multiple buildings were blown out. Two people are confirmed dead. Police are calling it a bombing.
At some point after the explosions, shots were fired at a politically-oriented youth meeting on Utoya island, just off the coast of Oslo by a man disguised as a police officer. The meeting was well-attended by the Labor Party, the party currently in power in Norway.
Right now, most other details are still very, very sketchy.
EDIT: The death toll now sits at seven.
