Norway attacks: Police publish names of terror victims

Norway's police have published the names of four of the 76 victims of Friday's mass killings in Norway carried out by Anders Behring Breivik.

They include three people killed in the Oslo car bomb and a 23-year-old man who died on an island nearby where Breivik went on a shooting spree.

The BBC's James Robbins reports on the aftermath of the attack and what is known about the man behind it.
