North Korea launched two suspected missiles Thursday, five days after firing off multiple "projectiles" including its new tactical guided weapon, widely agreed by experts to be a short range ballistic missile (SRBM).

The launches took place at 4:29 p.m. and 4: 49 p.m., respectively, from around Kusong in North Pyongan Province and landed in the seas off its east coast, according to the Republic of Korea Joint Chiefs of Staff (JCS).

The JCS said one flew about 270 kilometers and the other, 420 kilometers, both at an altitude of around 50 kilometers.

Cheong Wa Dae expressed concern over the launches, saying they did not help ease military tension on the peninsula.

President Moon Jae-in said they would be a violation of United Nations sanctions if the projectiles were identified as ballistic missiles ― even short-range ones ― in a special interview with public broadcaster KBS celebrating the two-year anniversary of his administration.
