No NK submarine seen on the night
There is a "low possibility" that Pyongyang would deploy submarines as a "means of invasion," the defense ministry said in an unusually lengthy statement, apparently drawn up to address growing suspicions over the cause of the incident.
"We, however, are continuing to watch North Korea closely and plan to reveal the outcome of the investigation [on the cause of the explosion] to the public in detail," it added.
The 1,200-ton Navy corvette Cheonan sank after an explosion tore it apart near the tense maritime border with North Korea, sparking initial suspicions of a torpedo attack by the reclusive dictatorship.
Among the 104 crew who were on board, 58, including the captain, were rescued, while 46 remain missing as prospect for their survival grows dim.
