Five people have been killed and two more injured in Norway after a man used a bow and arrow to attack them.
Police received word of an attack in the town of Kongsberg, south-west of the capital Oslo, on Wednesday.
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.
Prime Minister Erna Solberg said reports of the incident were horrifying.
The attacker is said to have launched the assault inside a supermarket.
One of those injured was an off-duty police officer who was in the shop at the time.
