At about 14:07 that day the armed bandits of the puppet army intruded into the DMZ south of Marker No. 1270 of the Military Demarcation Line and fired 90 mm recoilless gun toward a civil police post of the north side, thus seriously threatening the safety of civil policemen of the north side on routine duty.

This was a premeditated provocation of the south Korean puppet forces designed to deliberately aggravate the situation in the DMZ of the MDL.

The touch-and-go situation was prevailing there owing to such undisguised military provocation committed under the eyes of the north.
