BREAKING: Man armed with bow and arrow kills several people in Norway

"The man has been apprehended … from the information we now have, this person carried out these actions alone," police Chief Oeyvind Aas told reporters at a Wednesday night news conference. Aas declined to specify how many have died but said, "several people have been injured and several are dead."

While police typically remain unarmed, officers were immediately ordered to carry weapons nationwide when the attacks were reported. "This is an extra precaution. The police have no indication so far that there is a change in the national threat level," the directorate said in a statement.

Norway's minister of justice and public security, Monica Maeland has received updates on the attacks and closely monitor the situation.

Kongsberg is 68 kilometres west of Norway's capital, Oslo and is home to 28,000 residents.

This is a breaking story and will be updated as more details are made available.
