Over the weekend, Swedish Rear Adm. Anders Grenstad confirmed to the media that the apparent Russian submarine spotted in Swedish waters on October 31 was just a civilian working boat. The conclusion was reached after close examination of pictures taken by a former naval officer. But the Swedish military remain steadfast in its claim that Russia was indeed sailing submarines around Swedish waters last year: "The assessment that Swedish territory was violated in October 2014 remains correct in its entirety." In an extraordinary retort, the Russian foreign ministry issued a statement decrying "anti-Russian hysteria and propaganda" in Sweden's response to the mistaken submarine sighting.
