SEOUL - The armed forces of the Democratic People's Republic of Korea (DPRK) conducted a multiple-rocket launching drill Monday morning, the official Korean Central News Agency reported, in response to the United States-Republic of Korea (ROK) combined air drill a day earlier.

The long-range artillery unit of the Korean People's Army (KPA) on the western front fired two rocket shells of 600mm multiple-rocket launchers towards the eastern waters, the state news agency reported Monday.

According to its previous reports, the DPRK fired a Hwasong-15 at Pyongyang International Airport towards a pre-set area in the eastern open waters on Saturday

The multiple-rocket launcher was lauded as "the latest type of multiple launch precision attack weapon system" and "a tactical nuclear attack means" assigned to destroy enemy operational airfield, the report said.

The state media also said the US and the ROK have already staged combined air drills several times this year alone, adding fuels to the simmering tensions on the Korean Peninsula.

The KPA rocket firing came on the same day as a senior DPRK official delivered a second stern warning in two days.

In a sharp rebuttal against suspicions by the ROK over the preparedness of DPRK missile forces as shown by its Saturday launch of an intercontinental ballistic missile, Kim Yo Jong, vice-department director of the Central Committee of the Workers' Party of Korea, issued a press statement, saying the country "has possessed satisfactory technology and capabilities," the state news agency said in another Monday report.
