Who is Norway shooting suspect Anders Behring Breivik?

Norwegians are mourning the victims of a massacre at an island youth camp and a bombing in the capital Oslo.

At least 85 people died when a gunman opened fire at the Utoeya camp on Friday, hours after a blast in the government quarter killed seven.

Police have charged, a 32-year-old Norwegian man, with both attacks.

The BBC's Frank Gardner reports on the man at the centre of the investigation.
