91 people were killed in Norway when a gunman opened fire at a holiday camp just hours after a bomb exploded outside the Prime Minister’s Office, according to reports.

A 32 year old Norwegian man has been arrested in connection with both attacks.

Anders Behring Breivik was posing as a policeman when he killed ten teenagers as they ran for cover and tried to swim for safety.

The incident took place at a holiday camp that was organised by the Labour Party on Utoeya island, 25 miles North of Oslo.

Prime Minister, Jan Stoltenberg had been due to give a speech on today to the 560 people attending the youth camp.

Norwegian police said they feared there could also be explosives on the island, which has slowed down their search of the area.

Prior to the shootings, a car bomb exploded outside the Prime Minister’s office, ripping apart the centre of Oslo and killing and injuring 17 people. Stoltenberg was away at the time. A man matching Breivik’s description had been seen in the city centre before the blast, raising speculation that he carried out both attacks.

Prior to the shootings, a car bomb exploded outside the Prime Minister’s office, ripping apart the centre of Oslo and resulting in a number of casualties and causing extensive damage to the area. Stoltenberg was away at the time. Police are understood to have searched a flat in west Oslo where Breivik lived for more evidence.

Many theories have been put forward from home-grown terrorism to Jihadist terrorism. Norwegian officials are working with foreign intelligence agencies to see if there there was any international involvement in the attacks, according to reports.

Norwegian Police have requested that, where possible, people stay away from the centre of Oslo. British nationals are advised to exercise caution, monitor local media reporting and follow advice given by the emergency services.

An exclusion cordon continues to be in effect around the Government district in Oslo (affecting the Prime Minister’s Office, Ministry of Petroleum and Ministry of Finance) and there is a heightened level of security across the city. Currently public transport is operating normally except through the Government district.

Around 250,000 British tourists visit Norway every year. More than three million guest nights are spent in the hotels of Oslo, and the city is rapidly becoming a considerable, European tourist destination.
