Hundreds of North Koreans appear to have begun marching training for a paramilitary parade scheduled to be held in the capital next month, according to NK Pro analysis of satellite imagery.

PlanetLabs satellite imagery shows what appear to be troops in lines and block formations at the Mirim military parade training complex in Pyongyang on Aug. 17. The base is a replica of Kim Il Sung Square, where North Korea regularly holds military and paramilitary parades.
