AKIPRESS.COM - Another drone was found on a mountain near Seoul, South Korea's capital, after the defense ministry concluded three drones discovered in March and April were flown by the Democratic People's Republic of Korea (DPRK), Xinhua news agency reported Wednesday.

A flying object, believed to be an unmanned aerial vehicle (UAV) , was found on Mount Cheonggye, southeast of Seoul, military officials was quoted by local media as saying.

An unidentified hiker reported it to the police, who transferred it to the military. A military investigation team was dispatched to the scene to recover and examine where it came from.

The UAV was similar in color with the three drones, which the South Korean military claimed came from the DPRK, but it was different in shape with the three drones.

The South Korean military said last Thursday that the three drones were programmed to take off from and return to the DPRK based on investigation into built-in memory chips, calling the pre- arranged coordinates as "smoking gun" to prove the drones came from the DPRK.

The drones were equipped with digital cameras, capturing images of military installations near the Demilitarized zone and the Blue House in Seoul where President Park Geun-hye's residence and office are located.
