North Korean leader Kim Jong-un has ordered his top military officials to strengthen the regime's defense capabilities.
The North's state-run media KCNA reported Friday that Kim presided over a three-day meeting from June 21st to 23rd, and approved plans to provide what was referred to as a "military guarantee" to strengthen the regime's war deterrent.
Also during the meeting, North Korea made a rare mention of revising its war tactics.
The state media said Pyeongyang has decided to bolster the duties of its frontline units, with "an important military action plan."
But it did not offer any further details.
The latest meeting has been closely watched amid speculation that Pyeongyang has been preparing to conduct its first nuclear test in five years.
But, state media did not mention anything about its nuclear program being discussed in the meeting.
South Korea's Unification Ministry said it will continue to keep a close eye on the situation in the North.
"State media reports of the meeting did not directly mention anything about a nuclear test. But, because the North did announce that it has reviewed and approved an important plan to strengthen war deterrence our government will closely monitor the situation, while being prepared for all possibilities."
Some analysts say that the North's latest decision to revise war plans and add frontline army duties, apparently targets South Korea.
It's possible that North Korea could deploy its tactical nuclear weapons such as its short-range ballistic missiles like KN-23s or KN-24s to its frontline artillery units.
