SEOUL -- A North Korean drone that entered South Korean airspace last month was possibly conducting video reconnaissance of the presidential office, security officials in Seoul have said, creating a potential new danger.
South Korea's National Intelligence Service said it could not rule out the possibility that the drone -- one of five that crossed into the South on Dec. 26 -- was conducting reconnaissance. Although no classified information was stolen, Pyongyang has demonstrated the ease with which drone cameras could capture information about important security facilities.
