Norway PM: This is a national tragedy

At least 85 people died when a gunman opened fire at an island youth camp in Norway, hours after a bomb attack on the capital, Oslo.

Officers have charged a 32-year-old Norwegian man in connection with Friday's attacks.

The man was arrested on tiny Utoeya island outside Oslo, where police say he opened fire on teenagers. The Oslo bomb attack killed at least seven people.

Prime Minister Jens Stoltenberg, whose offices were among those badly hit by the blast, described the attacks as a "nightmare" and a "national tragedy".
