North Korean leader Kim Jong-un inspected the missile drills, DW reported.
'South Korea's Joint Chiefs of Staff said in a statement that the two missiles were fired from the northwest area of Kusong, in an easterly direction, before falling into the sea. The missile launches came after North Korea carried out a military drill and fired multiple projectiles on Saturday. They also coincided with the arrival of Stephen Biegun, the US special envoy to North Korea, in Seoul for talks with South Korean authorities. South Korea's presidential Blue House dubbed the missile launches "very worrisome" and a setback to peace efforts on the Korean Peninsula', wrote the news agency.
At least two short-range projectiles were used; the press did not initially disclose if it were shells or missiles.
Earlier, Pyongyang warned that it would resume the policy of strengthening its nuclear arsenal unless the U.S. changes its stance towards applying sanctions against the DPRK.
