Church services are taking place in Norway today to remember the victims of the gun and bomb attacks on Oslo and the island of Utoeya.

The attacks one year ago by Anders Behring Breivik killed 77 people, mostly young people connected with the Labour Party taking part in a summer camp on the tiny island.

Breivik has admitted carrying out the attacks and is currently on trial.

Thousands were expected to attend a memorial service taking place this morning in the cathedral in Oslo.

Among those in attendance were members of the Norwegian Royal family, political leaders and survivors of the attacks.

Prime Minister Jens Stoltenberg laid a wreath at the site of the Oslo bombing this morning and was then to travel to Utoeya to give a speech to Labour Party youth.

He was to lay a wreath on the island at 18:45 local time, marking the moment Breivik was arrested last year.

Another memorial service was taking place today in Hole church, close to Utoeya.
