A bomb rocked downtown Oslo Friday and a gunman opened fire on a children's camp run by Norway's Labor Party.  At least seventeen people were killed in the attacks, reported CNN.

A 32-year-old Norwegian man is in custody, officials said.  Police claim that the attacks are definitely related.

The explosion took place near Prime Minister Jen Stoltenberg's office.  Norwegian media said that Stoltenberg and his Cabinet members were unharmed.

A gunman dressed as a policeman went on a shooting spree at a youth camp on an island outside of Oslo.  Police said nine or 10 people died in the attack.

Reporter for Swedish newspaper Aftonbladet Mattias Carlsson told the Miami Herald in a phone interview that more than a dozen bodies lay on the shore or were floating in water.

There are four people and they are lying together as if they are hugging, Carlsson said.

Video footage showed people running to safety from Oslo's downtown.  One building was on fire and a massive amount of smoke was rising toward the sky.  At least 15 people were hurt in the blast.  Car wreckage was found near the site of the blast.

Norway was singled out as a target by Al Qaeda but nobody claimed responsibility.
