North Korea will use its nuclear weapons to “annihilate” the South Korean army if they ever launch a primitive strike, King Jong-un’s sister said on Tuesday, according to state media.

In a statement carried Tuesday by North Korea’s state media, Kim Yo Jong called South Korea Defense Minister Suh Wook’s recent comments about preemptive strikes a “fantastic daydream” and the “hysteria of a lunatic.”

She stressed that North Korea doesn’t want another war on the Korean Peninsula but warned it would retaliate with its nuclear forces if the South opts for preemptive strikes or other attacks, which would leave the South’s military “little short of total destruction and ruin.”

This is the second time this week, the powerful sister of North Korean leader Kim Jong Un, who also holds several senior positions in the government and the ruling party, berated South Korea for touting its supposed preemptive strike capabilities against the North.

Seoul had issued a low-key response following Kim’s earlier comments on Sunday, urging Pyongyang to refrain from further raising tensions and return to dialogue.

The flurry of exchanges between the two Korean nations comes in the backdrop of North Korea launching a series of ballistic missile tests, raising concerns among the South Korean establishment and the West.
