Pyongyang, March 15 (QNA) - North Korea has carried out military exercises using high-precision 600mm multiple rocket launchers, a day after launching more than 10 ballistic missiles toward the sea, state media reported.

According to the Korean Central News Agency (KCNA), a long-range artillery unit of the North Korean army in the country's western region conducted the drills using 12 high-precision 600mm multiple rocket launchers and two artillery companies. 

The exercises were overseen by North Korean leader Kim Jong Un. 

On the previous day, the military of South Korea detected the launch of multiple missiles from near the North Korean capital Pyongyang toward the East Sea. The missiles reportedly traveled about 350km.
