North Korean leader Kim Jong Un threatened to use nuclear weapons to destroy South Korea if attacked, state media reported Friday, after South Korea’s president warned that if the North used nuclear weapons it would “face the end of its regime,” CNN reports.

 

The fiery rhetoric isn’t new, but comes at a time of tension on the Korean Peninsula and just weeks after North Korean state media released images of Kim visiting a uranium enrichment facility, which produces weapons-grade nuclear materials.

 

While touring an army base in the western part of the country Wednesday, Kim said if the South were to encroach upon the North’s sovereignty, Pyongyang “would use without hesitation all the offensive forces it has possessed, including nuclear weapons,” the state-run Korean Central News Agency reported Friday.

 

“If such situation comes, the permanent existence of Seoul and the Republic of Korea would be impossible,” Kim added, using the proper name for South Korea.

 

Hostilities between the two Korean leaders have been simmering this year as North Korea has appeared to have intensified its nuclear production efforts and strengthened ties with Russia, deepening widespread concern in the West over the isolated nation’s direction.

 

Kim’s comments appeared to come in direct response to South Korean President Yoon Suk Yeol, who on Tuesday showcased Seoul’s most powerful ballistic missile and other weapons designed to deter North Korean threats during a parade for Armed Forces Day.
