North Korea’s newest naval destroyer, a 5,000-tonne warship launched in the city of Chongjin, suffered a catastrophic accident that left it lying sideways in the water, according to South Korean officials. The accident happened at a launch ceremony with leader Kim Jong-un in attendance. Kim, reportedly furious about the launch failure, has called it a “criminal act”.
