SEOUL - The Democratic People's Republic of Korea (DPRK) fired two unidentified projectiles into the eastern waters on Monday, according to the Joint Chiefs of Staff (JCS) of the Republic of Korea (ROK).

The JCS said in a statement that the projectiles were launched near the DPRK's east coastal town of Wonsan toward the East Sea at about 12:37 pm local time.

The projectiles flew about 240 km at an altitude of around 35 km. The intelligence authorities of the ROK and the United States are making a precision analysis on further details, the JCS noted.

It was the DPRK's first launch of projectiles this year. During the latest test-firing on Nov. 28 last year, two projectiles were launched from the DPRK's eastern province of South Hamgyong towards the eastern waters.

The JCS said the ROK military maintained a defense posture while closely monitoring relevant situations in preparation for possibly additional launches.

It urged the DPRK to immediately stop such acts that are of no help for efforts to defuse tensions on the Korean Peninsula.

Chung Eui-yong, top national security adviser for the ROK President Moon Jae-in, chaired an emergency video teleconference with the defense minister and the intelligence agency chief to review the overall security situations around the peninsula, including the DPRK's projectile launch earlier in the day.
