SEOUL, Dec. 11 (Yonhap) -- North Korea is believed to be disassembling a long-range rocket, a senior military source in Seoul said Tuesday, a day after Pyongyang announced it will extend its 13-day launch window due to technical problems.
According to analysis of the latest satellite image, scientists and workers have begun taking apart the three-stage rocket from the launch pad at the Dongchang-ri site in the country's northwest.

"We detected the signs of (North Korea) breaking apart the rocket at the Dongchang-ri launch site. It seems that the North's trying to fix technical problems," the source said, asking anonymity, without elaborating.
