On 21 December, the vessel Thor Liberty from Germany and flying the British flag was seized by Finnish customs at the port of Kotka, suspected of illegal arms exports, customs discovered on board with 69 missiles U.S. Patriot air and 150 tons of explosives. The ship was to carry the missiles in South Korea. A few days later, the authorities allowed the ship to sea again, having seized the cargo, however, because of the lack of documentation for international transit of the cargo.
Soon after, Seoul to Helsinki asked to issue the necessary documents, indicating that the ship had been in the Finnish port because it sought refuge in a storm at sea.
According to Seoul, the transaction between Germany and South Korea was conducted as part of a legal sale on the basis of an intergovernmental agreement.
