A new 5,000-tonne destroyer key to North Korea’s naval advancement was damaged during its launching ceremony attended by leader Kim Jong Un, state media reported.

The ship slid off the ramp and became stuck after the flatcar failed to move alongside it, throwing off its balance and crushing parts of the ship’s bottom, according to the Korean Central News Agency (KCNA).
