Doctors have made an assessment on site, says Jonas Franzén, press spokesperson at the Swedish Maritime Administration, to TT.
One person was winched up to a helicopter and taken to hospital, and the others were transported by other military boats to land where ambulances met them and took them to hospital, he continues.
The accident with the combat boat, which belongs to the Älvsborg Amphibious Regiment, occurred at 20.15 on Tuesday.
We are conducting training for combat boat operators right now, so this is connected to that, says Johanna Frejme, communications manager at the Älvsborg Amphibious Regiment, to TT.
She says that four people were on board. They have been taken to hospital for care and control. The extent of their injuries is not known.
The combat boat had run aground. Johanna Frejme has no information about how the accident occurred and if the speed was high.
I don't know anything about it yet, but we'll take that into the investigation we're starting.
According to Jonas Franzén, the Swedish Maritime Administration has handed over the case. The Swedish Armed Forces are responsible for the boat. It did not sink in connection with the accident, he says.
But it's quite badly damaged.
The police will also investigate the accident. Göteborgs-Posten writes that police officers were transported by military boat to the accident boat.
We will initiate a preliminary investigation regarding a workplace accident, says officer on duty Sebastian Börjesson to the newspaper.
