North Korea announced on Wednesday that more than one million young people had volunteered to join the army this week.

Millions of young people have joined the nationwide struggle to get rid of the scum of the Republic of Korea who committed the provocative and dangerous act of violating the sovereignty of the DPRK by infiltrating drones.

More than 1.4 million Youth and Students Association officials from across North Korea volunteered to join or return to the KPA on 14 and 15 October, the official Korean Central News Agency (KCNA) said.

North Korea imposes compulsory and lengthy military service on all men and has previously announced waves of volunteers during periods of high tension with Seoul or Washington.

Pyongyang on Tuesday blew up symbolic roads and railways linking the two Koreas, warned that any drone overflights would be a declaration of war and ordered soldiers stationed at the border to prepare to open fire, AFP reported.
