This was reported by the Ronhap agency, citing a source.
It is assumed that this could be an explosion of the inter-Korean communications office located on the territory of the complex.
Earlier it was reported that the DPRK decided to terminate the communication lines with South Korea, saying that Pyongyang has nothing more to discuss with Seoul at the negotiating table.
Later it became known that the DPRK was studying the possibility of introducing troops into the zones demilitarized in accordance with the inter-Korean agreements.
