Working-level military officers from North Korea and South Korea met Monday to discuss improving their lines of communication amid strained ties between the divided nations, officials said. It would be the second official talks between South and North Koreas since conservative government was inaugurated in Seoul in February, Associated Press reported. On Monday, the sides met in a location inside the demilitarized zone bisecting the Korean peninsula, said Won Tae-jae, a spokesman at the South Korean Defense Ministry, during a media briefing. He did not provide details, saying he would brief the results of the meeting later in the day. Earlier Monday, ministry officials said the sides planned to discuss how to overhaul and upgrade military communication lines between the countries. The two Koreas have operated nine military hot lines but some of them are now out of service for technical reasons, according to the Defense Ministry.
