NKorea Says Another SKorean Drone Entered its Airspace

North Korea said on Saturday that South Korea flew another drone into its airspace on January 4, infringing on its sovereignty, according to state media KCNA. The announcement, which comes before North Korea holds a key party congress that will lay out policies for the next five years, sets the stage for cementing leader Kim Jong Un's rhetoric that South Korea is a foreign and hostile nation, an analyst said.
