North Korea may have decided to reschedule its planned rocket launch apparently due to technical problems, Yonhap news agency quoted a senior government source in Seoul as saying Sunday. The North's Korean Central News Agency (KCNA) said earlier in the day Pyongyang was considering postponing the dates of its rocket launch, scheduled for between December 10-22, providing few details. The announcement sparked speculation over the latest development as recent satellite images showed that the North has installed all three-stages of the long-range rocket on the launch pad in its northwestern tip and was preparing for fuel injection, despite mounting international pressure. The government source familiar with the matter said the North is considering delaying the launch date due to "technical problems," saying "abnormal signs" have been spotted since Saturday afternoon. He didn't elaborate.
