South Korea's military was behind a drone incursion into Pyongyang, the capital of the Democratic People's Republic of Korea (DPRK), the DPRK's official Korean Central News Agency (KCNA) reported on Monday.

The drone was sent to scatter anti-DPRK leaflets, reported the KCNA, citing the results of an investigation released a day earlier by a spokesman for the country's Ministry of National Defense.

The conclusion was made by a joint investigation group composed of officials from the Ministry of National Defense and the Ministry of State Security, among other relevant specialized institutions, after what KCNA said was a comprehensive analysis of the flight plans and logs obtained from the flight control module found in the remains of a crashed drone.

South Korea's military said the DPRK's claim was "unworthy" of verifying or responding to, according to Yonhap News Agency.

The KCNA report offered a detailed flight record showing that after taking off at Paekryong Island on the evening of October 8, the drone flew over Jangyon County of South Hwanghae Province and the waters around the Cho Islet and then to the waters around Namjoap Islet, before it flew over Chollima District, Nampho Municipality and intruded into the DPRK's capital.

The drone scattered political leaflets in the area between the office of the DPRK Foreign Ministry and a Pyongyang metro station called Sungri and around the office of the Ministry of National Defence early on the morning of October 9, according to the KCNA report.
