Tense negotiations between North and South Korea continued through the night as Seoul demanded a formal apology for injuries to two of its soldiers this month, South Korean officials said Monday, NBC News reported.
The talks were described as tense after South Korea's Defense Ministry said it had detected "unusual" North Korean submarine activity even as the countries are trying to resolve a spat that brought the peninsula close to war last week.
Official sources said South Korean President Park Geun-hye told her staff during a meeting Monday morning that "it is most important to get North Korea's apology" for injuries to the two soldiers, who were wounded by landmines along the border early this month.
