A security guard has described the trauma of seeing last July's car bomb blast set off by Anders Behring Breivik at Norway's government headquarters.
Tor Inge Kristoffersen told the Oslo court he watched on CCTV as a van parked and a man wearing what looked like a guard's uniform got out.
Mr Kristoffersen said he zoomed in on the number plate before the vehicle exploded killing eight people.
Breivik has admitted the bombing and subsequent shootings on Utoeya island.
