Strong winds
On Saturday, an official at Vladivostok's maritime rescue centre, Vladimir Yeroshkin, said the Lida Demesh had been detained and boarded by the North Korean coastguard about 3-5 nautical miles (5.5km) from Cape Musudan."An armed group boarded the ship and ordered the captain to change course and go to a North Korean port [Chongjin]," he told the Russian NTV network.Mr Yeroshkin said the centre had been told the ship's 25 crew-members were fine and that there had been no threat to their lives.North Korean officials in Russia said they were not aware of the reasons for the detention, but Mr Yeroshkin said strong winds might have accidentally forced the vessel into North Korean territorial waters."The forecast for our region is a N-NW wind, 15-18 metres per second," he said."This is a small two-hold ship. It is quite possible that weather conditions forced it to move closer to the coast."Most countries claim an area extending 12 nautical miles (22.2km) from their coast as territorial waters.
