It was said that there was a movement to prepare something on site from yesterday before North Korea detonated the liaison office building today (16th). We will connect this report by linking reporters from the Ministry of National Defense.

Reporter Taehoon Kim, what was the specific movement in Gaesung, North Korea?

<Reporter>

Yes, yesterday, it was caught by our intelligence authorities that the trucks loaded with manpower and equipment gathered at the Gaeseong inter-Korean joint office.

A military source said, "We can't specify the date of the bombing, but we have strengthened surveillance since yesterday because North Korea is expected to bomb the liaison office soon."

North Korea now promises to send its troops back to the demilitarized zone, to make it a fortress.

<Reporter> The

announcement by the General Staff of the North Korean Army is expected to restore 10 GPs of North Korean troops that were demolished in November 2018 under the agreement of 9/19, and also to heavily arm the North Korean troops in the Panmunjom Joint Security Area, which was almost disarmed.

So far, there has been no news that unusual trends have been identified in the forward GP and joint security zones.

The GP is on a rugged hill, so it is difficult to recover, so it will take a while to fortify again.

However, the North Korean military's re-arrangement of the Joint Security Area is something that can be done in an instant, so the military is polite to the North Korean military in the Joint Security Area.

Along with this, North Korea can now proceed with further provocations, and these concerns continue to arise, and how is our military responding to this?

<Reporter>

Watchcon, the watchdog of North Korea, and Defcon, ready for battle, remain the same.

The bombing of the joint contact office is not a direct act of hostility by the North Korean military, so the official surveillance and combat situation remain the same.

However, as the North Korean military announced the fortification of the Demilitarized Zone, it is strengthening its surveillance against the GP and common security zones and preparing for accidental provocations.

Missile bases such as Wonsan and Sinpo are also noticed, but military officials said there are no signs so far.

The Pentagon says North Korea will respond strongly if it conducts military provocations.
