A report by the AP said that the Finnish military says it has dropped depth charges onto a suspected submarine in the sea outside Helsinki after twice detecting the presence of a foreign object in the area. The navy's maritime operations chief, Olavi Jantunen, says they could not identify the "underwater object" but had begun an investigation, which could take weeks. “We strongly suspect that there has been underwater activity that does not belong there. Of course it is always serious if our territorial waters have been violated,” Defense minister Carl Haglund told Finnish news agency STT. A UPI reports quotes Navy chief of staff Admiral Juha Vauhkonen saying that it’s not yet possible to say whether or not the underwater object detected in waters near Helsinki was a submarine.
