There are three things immediately wrong with this statement:
- Portugal did not make it into the Round of 16
- North Korea is not in the 2014 World Cup
Considering North Korea's penchant for reporting sports news that exists outside of space and time, you wouldn't be surprised that its state news service is at it again. It showed up on Reddit and several news sites (including ours). But there's enough chatter to suggest that it may be a clever parody video.
North Korea did compete at the World Cup in 2010, finishing with three losses.
