North Korea seen preparing long range missile sites

North Korea appears to be preparing two sites from where a long-range missile could be launched, according to an article on Voa News website.



South Korea\'s Chosun Ilbo newspaper quotes an unidentified government official as saying that a special train used to carry a long-range missile has been spotted on the move.



The report says the train has been seen moving from a missile launch sites on North Korea\'s north-western coast to its north-eastern coast. A similar report was carried by Japan\'s Sankei newspaper.



United States (U.S.) president Barack Obama met with his South Korean counterpart Tuesday to discuss the recent rise in tensions. After meeting with South Korean president Lee Myung-bak, Mr. Obama warned that a nuclear-armed North Korea is a \"grave threat\" to the world.



Mr. Obama has said he will end what he calls North Korea\'s cycle of starting a world crisis and then being rewarded with food and fuel for backing down, only to start up again. The president promised there will be vigorous enforcement of United Nations sanctions against the north, which were approved late last week in response to Pyongyang\'s nuclear test.
