Two people were killed and 14 people injured, several seriously, in shootings near bars in central Oslo overnight Friday into Saturday, said Norwegian police, who arrested a suspect.
The shooting took place around 1 a.m. local time at three nearby locations, including a gay bar in the center of the Norwegian capital.
Police reported two dead and 14 injured and said two guns had been confiscated.
“Everything now indicates that there was only one person who made this gesture,” said a police officer, Tore Barstad, during a news conference.
However, the workforce in the capital has been reinforced to deal with other incidents, he added, without specifying whether it was an act of terrorism.
Police received the first reports at 1:14 a.m. and the suspect was arrested five minutes later, he said.
The shooting took place near the London Pub gay club, Mr Nilsen Jazz Club and a diner.
Police officers gathered to reflect on the impact of the shooting on the staging of the Pride march to be held in Oslo on Saturday afternoon.
“He looked very determined where he was aiming. When I understood it was serious, I ran away. There was a bleeding man on the ground,” a witness to the scene told the newspaper Verdens Gang (VG).
Another witness mentioned to VG the use of an automatic weapon – information that the police did not confirm – and spoke of “a theater of war”. “There were a lot of casualties on the ground who had head injuries,” he said.
According to an NRK journalist present at the time of the shooting, the shooter came with a bag from which he pulled a gun, which he fired.
The area was patrolled by heavily armed police officers dressed in bulletproof vests and helmets.
Of the 14 injured, eight were taken to hospital and six others were treated by paramedics.
“Some are described as having serious injuries and others as having minor injuries,” police officer Tore Barstad said.
Generally peaceful Norway was the scene of bloody attacks on July 22, 2011, when right-wing extremist Anders Behring Breivik killed 77 people in a bomb attack on the government building in Oslo and a shooting attack on a young workers’ rally on the island of Utoeya.
