Cheong Wa Dae was set to convene a session of the presidential National Security Council (NSC), Sunday to discuss North Korea's weekend launch of two missiles.

Suh Hoon, director of national security at the presidential office, plans to preside over the NSC session after the North's state media reported the country had test-fired a new tactical guided weapon to improve the efficiency of tactical nuclear operations.

South Korea's military said that it had detected the North's launch of two missiles into the East Sea at 6 p.m. Saturday. They flew 110 kilometers at an apogee of around 25 km and a top speed of Mach 4, it added.

Following a briefing on the launch, President Moon Jae-in directed the military to exhaustively check North Korean military movements and thoroughly manage the security situation, his aides said.
