North Korea is preparing to launch rockets, CNN reported.

Satellite images of DigitalGlobe made at the end of February appeared at the disposal of the radio station. The footage captured the research center Sanumdong, where they produced the country's first intercontinental ballistic missiles. There are railway wagons and cranes at the sorting station not far from the center, and cars and trucks are parked right next to the enterprise.

"We're seeing a lot of vehicle activity at the Sanumdong facility and also at the rail transfer point where it would be loaded and taken to Sohae," said Jeffrey Lewis, director of the East Asia Nonproliferation Project at the Middlebury Institute of International Studies at Monterey, who has studied the new images.
