OSLO, Norway (AP) - Oslo police officials say two people have been confirmed dead and 15 injured in a powerful bomb blast at the prime minister's office.
Police told reporters the explosion Friday was caused by a "one or more" bombs. They declined to speculate on who was behind the blast.
Asked if the blast was caused by a car bomb, Oslo police chief Anstein Gjengdal said: "It is possible that a vehicle has been used in this incident, but we can't confirm this."
He said that police have sealed off the office of Norwegian broadcaster TV2 to investigate a suspicious package there.
A Norwegian government official also was quoted as saying that people remain trapped in some buildings hit by the bomb blast.
Soon after the bomb attack, police are said they are sending anti-terror police to a youth camp outside Oslo after reports of a shooting there following the bomb blast at the government headquarters.
The news site VG reported that a man dressed in a police uniform opened fire at the camp. It says several people were injured.
Oslo police chief Anstein Gjengdal said anti-terror units were being sent to the camp at Utoya, outside the Norwegian capital.
He had no other information on that incident, which came hours after a bomb blast outside the government headquarters killed at least two people and injured 15.
