North Korean leader Kim Jong Un said his country will maintain its military buildup while asserting that his regime could "preemptively" use nuclear weapons, reports said.

Kim expressed a firm will to continue developing his nuclear-armed military so that it could preemptively and thoroughly contain and frustrate all dangerous attempts and threatening moves, including ever-escalating nuclear threats from hostile forces, if necessary, the North's official Korean Central News Agency said Saturday. The news agency said Kim called his military officials to praise their work during Monday's parade, where the North showcased the biggest weapons in its nuclear arsenal, including intercontinental ballistic missiles that could potentially reach the U.S. homeland.

North Korea had tested a series of missiles at the beginning of the year surprising experts. North Korea has conducted 13 rounds of weapons launches so far this year, including its first full-range test of an ICBM since 2017

Reports claim North Korea may be preparing a nuclear test as Kim this week reviewed North Korea's latest missiles during a parade including the intercontinental ballistic missile the Hwasong-17 missile.
