North Korea's second naval destroyer was damaged in a failed launch this week, state media reported Thursday, sparking fury from leader Kim Jong Un, who wants bigger warships to deal with what he calls escalating U.

Kim Jong Un was reportedly enraged by the "sheer carelessness" leading to the botched launch of the regime's second destroyer.

North Korean ruler Kim Jong Un said a new naval destroyer was damaged in a "serious accident and criminal act caused by absolute carelessness."
