North Korea's Kim warns South against 'double-dealing'

North Korean leader Kim Jong-un has warned South Korea against "double-dealing" by purchasing advanced weaponry amid peace talks between the two neighbors, as he attended the demonstration of a "new-type tactical guided weapon."

North Korea on early Thursday test-fired two new short-range ballistic missiles in a first since Kim's meeting with US President Donald Trump at the demilitarized zone (DMZ) between the Koreas last month, where they agreed to resume stalled denuclearization talks.

"We cannot but develop non-stop super-powerful weapon systems to remove the potential and direct threats to the security of our country that exist in the South," Kim said, according to state news agency KCNA.

The South Korean leader advised South Korean authorities to stop such "suicidal acts" and warned them that they "should not make a mistake of ignoring the warning."

He further said that he was "satisfied" with the new weapon's rapid response and low-altitude trajectory, which he said allows it to better evade air defenses.

The South's National Security Council said after the tests that it believed the missiles were a new type of ballistic missile, but the final assessment would be released after discussing the matter with the US.
