Newly released satellite pictures show signs that North Korea is preparing for a military parade to commemorate the new founding anniversary of its army. 

U.S. broadcaster Voice of America reported on Wednesday that the pictures show a large movement of soldiers at a square near Mirim Air Base in Pyongyang.

The satellite picture provider Planet filmed the air base at 10:16 a.m. Tuesday, and found that hundreds of vehicles were parked on one side of the square and troops were also seen to be moving in formation.  

The large-scale movement was reportedly spotted by South Korean authorities as well.

North Korea is forecast to be preparing for a ceremony to mark the newly designated founding anniversary of its military forces on February eighth, a day before the opening ceremony of the PyeongChang Winter Olympics. North Korea previously celebrated the occasion on April 25.
