Speculation is building that North Korea will unveil its latest weaponry at a huge parade this weekend to mark the 75th anniversary of the ruling Workers’ party.

The event, which will be keenly watched for signs of improvements in the regime’s nuclear and missile capabilities, is expected to be the biggest of its kind in the country’s history.

According to 38 North, a website that monitors North Korea, recent satellite images suggest the parade will feature thousands of goose-stepping troops, watched by their leader, Kim Jong-un.
