South Korea confirmed the notification by the Democratic People's Republic of Korea (DPRK) of cutting off military communications hotline.

"North Korea notified us of cutting the north-south military communications hotline through the notice under the name of the head of north-south general-level military talks," South Korea's Ministry of Unification said in a spokesman briefing on Wednesday.

The comments came after the Korean Central News Agency (KCNA)'s report that the DPRK sent the notice to South Korea at 11:20 am.

"The north-south military communications hotline that was set up for dialogue and cooperation between the north and the south lost its significance due to the reckless acts of the enemies," the KCNA reported. "Head of the north-side delegation to the north- south general-level military talks sent the phone notice to the south."

Around two weeks ago, the DPRK severed the inter-Korean Red Cross hotline in protest against the military drills between Seoul and Washington, including the two-month filed training exercise " Foal Eagle" and the computer-simulated war game "Key Resolve".

Pyongyang warned it will nullify the Armistice Agreement that ended the 1950-53 Korean War, vowing to nullify all non-aggression treaties.
