The worst weather in 15 years has trapped ships in the Baltic Sea. Unusual freezing conditions have meant that both cargo and passenger vessels have become stuck, and are waiting for icebreakers to free them. Over a thousand passengers are stranded, and the ships may have to be evacuated.
As well as a colder than normal winter, high winds are also hampering passage through the icy waters between Stockholm and the Aaland Islands.
The Swedish Maritime Administration did issue a warning about the bad conditions earlier this week, but it seems the advice was ignored by many operators. Four Viking Line ferries, which are used by people travelling between Finland and Sweden, are among the 50 vessels stuck in the sea.
Icebreakers have already started arriving, but the rescue is expected to take a very long time.
