SEOUL, March 24 (UPI) -- North Korean leader Kim Jong Un declared South Korea the "most hostile state" during a speech to the country's rubber-stamp legislature, state media reported Tuesday, reinforcing Pyongyang's hardening stance despite Seoul's push to revive inter-Korean dialogue.

Kim made the remarks Monday on the second and final day of the first session of the 15th Supreme People's Assembly, according to the official Korean Central News Agency.

"We will recognize South Korea as the most hostile state and deal with it by thoroughly rejecting and ignoring it through the clearest words and actions," Kim said.

He also warned that Pyongyang would make Seoul "pay a merciless price" if it provokes the North.
