At least four people were killed in the Norwegian town of Kongsberg by a man armed with a bow and arrows, according to local media.
The shootings were said to have taken place in a supermarket in the city, 80 kilometers southwest of Oslo.
Police chief Øyvind Aas said the man had been apprehended and “according to information we now have, this person carried out these actions alone,” Reuters reported.
The motive for the attacks was not clear, Aas said, but he did not rule out terrorism. “It is natural to wonder if this is an act of terrorism. But the man has not been questioned and it is too early to draw a conclusion.
