SEOUL, Dec. 12 (Yonhap) -- North Korea fired off a long-range rocket on Wednesday, a Seoul military official said, despite international pressure over the plan seen as a test for ballistic missile technology.
The move comes just two days after Pyongyang announced on Monday that it was extending the 13-day launch window by one week until Dec. 29 to fix a "technical deficiency" in the rocket's first-stage control engine module.
In a surprise move, the North fired off the long-range rocket from the Donchang-ri launch site at 9:51 a.m., which was immediately detected by the South Korean military.
"Shortly after the liftoff, Aegis radar system in the Yellow Sea detected the move," a senior military official said.
Since the North's announcement of the rocket launch, the South Korean military has deployed three Aegis warships, equipped with SPY-1 radar with a range of 1,000 kilometers, along the west coast and in southern waters to track the rocket's path.
On Tuesday, satellite imagery showed that the North removed the three-stage rocket from the launch pad, raising speculation that the move was connected with fixing technical problems.
