OSLO - A Russian fishing trawler which caught fire in Norway on Wednesday is now at risk of exploding, fire and rescue officials say.
Nearby schools have been closed and a 300-metre area has been cleared around the site in the port of Tromso, where emergency services are working to contain the threat.
It is not known what caused the fire.
Firefighters reportedly said the blaze began at the stern then spread to fishing nets.
But police have not confirmed this and are still investigating, Norwegian media say.
Norwegian police say all 29 crew members from the trawler, the Bukhta Nayezdnik, are safe, having been evacuated on Wednesday around 12:30 local time (10.30 GMT).
Two are receiving treatment for smoke inhalation, according to local reports.
Emergency services are hoping to prevent an explosion by cooling a large tank of ammonia inside the trawler - a gas which can cause skin burns and is dangerous to inhale.(FA)
