North Korea was detected making final preparations for a massive military parade ahead of the 90th anniversary of its Korean People's Revolutionary Army on Monday.

According to government sources on Sunday, the South Korean military and intelligence authorities are closely watching the situation under judgement that the North is likely to stage a military parade involving about 20-thousand military personnel at the Kim Il-sung Square in Pyongyang at around 12 a.m. Monday.

About 250 pieces of equipment were reportedly mobilized for rehearsals, in which the North appeared to have displayed what it claims to be a new hypersonic missile, as well as a Hwasong-17 intercontinental ballistic missile and a submarine-launched ballistic missile.

In particular, two floating bridges were reportedly built from the Kim Il-sung Square located on the west bank of the Taedong River to the Juche Tower located on the other side of the river. It is the first time that floating bridges were built over the river for a military parade.

North Korea is expected to showcase its new weapons and missiles in the planned military parade in a show of force.
