NORTH KOREAN leader Kim Jong Un has overseen the firing of two new air defence missiles, local media reported today.

The report on Sunday comes a day before United States President Donald Trump meets new South Korean leader, Lee Jae Myung, in Washington, DC.

North Korea’s Korean Central News Agency (KCNA) said the tests, which took place on Saturday, showed that the missiles demonstrated a “fast response” to aerial targets such as attack drones and cruise missiles.

The report said the new missiles “operation and reaction mode is based on unique and special technology,” but carried no further details about the system.

The missile test comes as South Korea and the US continue the latest of their latest joint military war games.

The South Korean military announced that it had fired warning shots at North Korean soldiers who were alleged to have briefly crossed the heavily militarised border last Tuesday.

The United Nations Command in South Korea put the number of North Korean troops that crossed the border at 30, according to the Yonhap news agency.

North Korean Army Lieutenant General Ko Jong Chol was quoted on North Korean media as describing the incident as a “premeditated and deliberate provocation.”

“This is a very serious prelude that would inevitably drive the situation in the southern border area, where a huge number of forces are stationed in confrontation with each other, to the uncontrollable phase,” General Ko said.

Earlier this month, Mr Kim slammed the US-South Korea joint military war games as “hostile and confrontational” to his country, pledging to speed up nuclear build-up.

South Korea’s new leader, Mr Lee, has sought warmer ties with the nuclear-armed neighbour, and has promised to build “military trust,” but Pyongyang has said it has no interest in improving relations with Seoul as long as it maintains close ties to the hostile US.
