DRPK fired four strategic cruise missiles into the sea, official television reported Friday, adding that the exercise "demonstrated once again Pyongyang's nuclear fighting force's war posture."

The four "Hwasal-2" missiles were launched from the Kim Chaek City area of North Hamgyong province into the East Sea, also known as the Sea of Japan, and "precisely" hit their target, according to the Korean Central News Agency (KCNA).

The launching drill proved the weapon system's reliability and tested the swift response of strategic cruise missile units, which are a crucial component of the Democratic People's Republic of Korea's nuclear deterrent capabilities, as per the news agency.

Before striking the target, the four launched strategic cruise missiles flew an oval and "8"-figure path simulating a distance of 2,000 kilometers placed on the East Sea of Korea for 10,208 to 10,224 seconds, the report detailed.

The report further revealed that the Workers' Party of Korea's Central Military Committee expressed tremendous satisfaction with the outcome of the launching drill.

This comes shortly after state-media Korean Central News Agency (KCNA) reported that the DPRK fired two short-range missiles on Monday after it had launched its powerful intercontinental ballistic missile (ICBM) last Saturday. 

As South Korea weaves closer ties with the US, DPRK's leader declared last year that his country is an "irreversible" nuclear power, conducting weapon tests nearly every month, including the launch of its most advanced intercontinental ballistic missile (ICBM).
