SEOUL, Jan. 10 (Xinhua) -- South Korean Defense Minister Ahn Gyu-baek on Saturday said allegations that South Korean drones violated the airspace of the Democratic People's Republic of Korea (DPRK) were "absolutely untrue," noting that the drone shown in photos released by Pyongyang was not a model operated by the South Korean military, according to Yonhap News Agency.

Ahn also said that a joint investigation between South Korea and the DPRK into the incident could be conducted.
