An explosion in Oslo and a shooting on the island of Utoya shook the country of Norway Friday. The attacks killed seven people and badly injured at least two others Friday at Norway’s government headquarters in Oslo and at the remote island of Utoya, where a Labour Youth summer camp was being held.

Norway Prime Minister Jens Stoltenberg was scheduled to talk at the Labour Youth camp on Saturday. He was not in the area of the Oslo explosion, and was unhurt, a government spokesman told the Associated Press. Police cannot confirm if anyone died in Utoya after a man disguised as a police officer entered the conference and started shooting. About 700 people, many teenagers between the ages of 14 and 18, were assembled at the camp.

Runar Kvernen, the police spokesman, said they did not know all the details, but a “very dramatic situation” was unfolding in Utoya.

In Oslo, police asked people to leave the downtown area, even though they said the area was now secure. Norwegian newspaper Aften Posten reports the attack targeted the Oil Ministry.

The police suspect a massive car bomb but do not know the cause, and no one has taken responsibility.

On cellphone footage captured moments after the blast, bystanders can be seen walking over broken glass. A YouTube user Negociosymercado recorded footage on his phone, saying people were in shock and that they never imagined an incident like this would happen in Oslo.
