As the story says, this seems "quite unusual" to me. Something shady is going on.
Police are questioning the crew of the MS Thor Liberty after what were described as 69 Patriot anti-missile missiles were found aboard.
Interior Minister Paivi Rasanen said the missiles were marked "fireworks".
The MS Thor Liberty had docked in the Finnish port of Kotka after leaving Germany last week.
Dock workers became suspicious after finding explosives poorly stored on open pallets, and the missiles were then found in containers marked "fireworks".
The managing director of the ship's owner, Thorco Shipping, expressed surprise. Thomas Mikkelsen told AFP news agency from Denmark that he was unaware of the matter.
Another company official, speaking on condition of anonymity, confirmed the ship had been detained in Finland and said the missiles could have been loaded on to the vessel by mistake, AFP adds.
Police did not confirm Finnish media reports that the ship had also been scheduled to stop in South Korea, Reuters news agency reports.
'Quite unusual'
The MS Thor Liberty left port in Emden, northern Germany, on 13 December and docked two days later in Kotka, southern Finland, to pick up a cargo of anchor chains, said Finnish Customs spokesman Petri Lounatmaa.
It was bound for the Chinese port of Shanghai but there was no indication for whom the military cargo was destined.
