William Scott, who was delivering goods in the area, told VG that he saw an injured woman lying on the ground.
“At first I thought it was a collision because there was a big pool of blood on the ground,” he said.
TV2 quoted an eyewitness as saying that the victims of the bloodshed came running from behind a convenience store. According to TV2, a pool of blood was seen in the asphalt.
The mountain village is located 80 kilometers (50 miles) north of Konsberg, where five people were stabbed and four others were injured when Aspen Andersen Brathen attacked strangers with a bow and arrow and a knife in October.
