Norway massacre: 'We were attacked by an insane maniac'

The man accused of a massacre at a youth camp in Norway and a bombing in the capital, Oslo, has admitted responsibility, his lawyer says.

Anders Behring Breivik, 32, described his actions as "gruesome but necessary", and said he would explain himself at a court hearing on Monday.

Thorbjorn Vereide who survived the attack describes how the suspect shot people who were trying to swim away from Utoeya island.
