Kim Jong-Un's sister sent a strongly-worded warning to the US and South Korea after the two countries carried out drills near the North Korean border.
Kim Yo-Jong, 33, is the younger sister of the despotic North Korean Supreme Leader.
Days after the US and South Korea made plans to practice military drills near the demilitarised border zone (DMZ) next week, Yo-Jong told the state TV network Pyongyang was planning a substantial response.
Yo-Jong said: "The United States and South Korea will face a more serious security threat by ignoring our repeated warnings to push ahead with the dangerous war exercises.
"Our government and military will keep a close eye on whether the South Koreans go ahead with the aggressive war exercises, or make a big decision.
"Hope or despair? That's not up to us."
North Korea is on the brink of a famine, with leading figures in the dictatorship drumming up nationalist rhetoric to distract the starving population.
The Supreme Leader's sister will succeed her big brother if he dies before his son turns 12.

Kim Jong-Un's family life is shrouded in mystery, with only one child confirmed but three widely believed to have been born.
South Korean intelligence sources suspect his eldest son is 11, so Yo-Jong is unlikely to ever become Supreme Leader as long as Kim Jong-Un continues to evade assassination.
Judging by her forceful rhetoric, that might well be a good thing.

She added in the TV broadcast: "We take this opportunity to warn the new US administration trying hard to give off powder smell in our land.
"If it wants to sleep in peace for coming four years, it had better refrain from causing a stink at its first step."
"South Korea has again chosen 'March of war' and 'March of crisis' instead of 'warm March' in front of all Korean people.
"Whatever the South will do by following its master, it will be not easy that the warm spring days of three years that it strongly wants will return."
The terrifying comments were translated by Seoul media org Yonhap News Agency.
