Norwegian police reported Saturday that two people were killed and 14 others were injured, some critically, in a shooting near bars in central Oslo.

Police revealed that a suspect was arrested following the shootings, which occurred around 1:00 a.m. (2300 GMT Friday) in three locations in the Norwegian capital, including a gay bar.

Two deaths and 14 injuries were reported, as well as the seizure of two weapons.

Police official Tore Barstad told reporters that “now everything indicates that there was only one person who committed this act." 

However, police numbers in the capital had been increased to deal with other incidents, he added, without specifying whether it was a terrorist act.

The shootings took place near the London Pub gay club, the Herr Nilsen jazz club, and a takeaway food outlet.

Police officers gathered to discuss the shooting's impact on the staging of Oslo's Pride march, which is scheduled for Saturday afternoon.

The scene of the shootings was patrolled by heavily armed police officers wearing bulletproof vests and helmets.

A woman who saw the incident said as quoted by the Verdens Gang newspaper that "He looked very determined about where he was aiming. When I realized it was serious, I ran. There was a bleeding man lying on the ground.”

Another witness quoted by the paper revealed the use of an automatic weapon -- which the police did not confirm -- and described it as "a war zone".

"There were a lot of injured people on the ground who had head injuries," he said.

The shooter arrived with a bag from which he pulled a weapon and began firing, according to an NRK radio journalist present at the time of the shooting.

Eight of the 14 injured were taken to a hospital, and six others were treated by medical service.

It is worth noting that this is not Norway's first shooting incident in recent years, as right-wing extremist Anders Behring Breivik killed 77 people in Norway on July 22, 2011.
