The Swedish Armed Forces are tracking a Russian submarine in the Baltic Sea, the army reported on Wednesday, adding that this is a routine operation, LETA reported citing AFP.
"A Russian submarine entered the Baltic Sea yesterday through the Great Belt" — the strait between the Danish islands of Langeland and Funen to the west and Lolland and Zealand to the east, — stated the Swedish army.
"Destroyers and military ships of the Armed Forces met the submarine in the Kattegat strait [between Denmark and Sweden] and are currently following it," the statement noted.
The army emphasized that this is a "routine operation that is conducted in close cooperation with our allies."
Since Russia's renewed invasion of Ukraine, tensions in the Baltic Sea have increased. Swedish Prime Minister Ulf Kristersson stated in January that Sweden is not at war, but the situation cannot be called peaceful.
Sweden abandoned its neutral status and joined NATO in March 2024.
Kristersson highlighted that the entire Baltic Sea region is subjected to hybrid attacks, pointing to disinformation and a series of incidents related to damage to underwater cables. "It is very likely that the Russian threat will be long-term. Our defense must be so as well," the Prime Minister stated.

Svenskt stridsflyg och örlogsfartyg mötte ubåten redan i Kattegatt och följer den på sin väg. En rutinverksamhet som sker i nära samverkan med våra allierade.
