Satellite images taken on Wednesday and analyzed by experts show “extensive preparations” for a planned rocket launch in North Korea in April, the Associated Press reports. “These pictures are new and important evidence that the North’s preparations for its rocket launch are progressing according to schedule,” said Joel Wit, a visiting fellow at Johns Hopkins. North Korea has said that the launch will take place between April 12 and 16. Any launch would end a Feb. 29 accord between North Korea and the U.S. that provides food aid for hungry North Koreans in agreement for suspension of nuclear work.
