Five people have been killed and two more injured in Norway after a man used a bow and arrow to attack them.
Police first received word of an attack in the town of Kongsberg, south-west of the capital Oslo, at 18:13 local time (16:13 GMT).
A Danish man aged 37 has been arrested on suspicion of carrying out the attack.
Police believe he acted alone, and will investigate whether it was an act of terrorism, a spokesman said.
Prime Minister Erna Solberg said reports of the incident had been “horrifying”.
“I understand that many people are afraid, but it’s important to emphasise that the police are now in control,” she told a news conference.
