OSLO, Norway -- A strong explosion rocked the old railway station in central Oslo Friday, killing one person, wounding 10 others and causing extensive damage, a police spokesman said.
Police said the explosion shattered windows and damaged lockers in the station.
There was no immediate indication who was responsible for the blast.
The bomb, apparently left in a locker off the main waiting hall, killed a young woman in her early 20s, and one of the 10 wounded was reported in 'serious' condition.
There were some 40 people in the area when the bomb exploded, and another 100 in nearby restaurants, the spokesman said.
Unconfirmed reports said witnesses saw two young men running from the scene after the explosion, and police had picked up a young man in his early 20s for questioning. Police, however, refused to confirm the report.
The old central station is mainly used for local traffic now. It adjoins the a newly built terminal.
