A gunman disguised as a police officer killed at least 10 people at a summer youth camp organised by Norway’s ruling Labour Party on an island on the outskirts of the capital Oslo, state television NRK reported yesterday.

“We have received information on the death of 10 people while seven have been wounded,” police spokesman Bjoern Erik Sem-Jakobsen was quoted as saying by the Nettavisen news website.

“This figure is still not definitive but that is what we have been able to establish so far,” he said.

At Utoeya, the idyllic island in an Oslo fjord, a man disguised as a police officer opened fire with an automatic gun as some 600 young people gathered for a summer school meeting of the ruling Labour Party’s youth branch. Prime Minister Jens Stoltenberg had at one point been scheduled to attend the event, police said.

“A man in police uniform called young people, telling them: ‘Come here’, and then executed them,” a witness told NRK.

Several of the youngsters tried to escape by jumping in the water.

Several witnesses told Norwegian media the man was of northern European appearance.

A man arrested by the police later yesterday, following the deadly shooting on Utoeya island and the bombing in Oslo, is a Norwegian, Justice Minister Knut Storberget said.
