Anders Breivik: how the campaign of murder unfolded

Anders Breivik's campaign of mass murder began with a bomb attack in Oslo and culminated in a massacre of young people on the island of Utoya.

Eight people died when his device went off at 3.26pm local time on July 22 last year.

Police described it as an "Oklahoma city-type" bombing. It targeted a government building using the same mix of fertiliser and fuel that blew up a building in the US in 1995.

The bomb was packed into a panel truck outside the building.

As police dealt with the aftermath of the bomb an even more deadly attack was about to begin 20 miles north-west of the capital.

Hundreds of young people were at a summer camp on Utoeya Island organised by the youth wing of the Labour Party.

At around 4.50pm he opened fire, claiming another 69 lives.

Survivors of the shooting spree described hiding and fleeing into the water to escape.

Police arrived on the island an hour and a half after the gunman first opened fire.

Breivik surrendered when officers finally reached him on Utoya at 6.35pm.
