SEOUL, South Korea, Oct 13, (AP): The powerful sister of North Korean leader Kim Jong Un on Saturday accused South Korea of deliberately avoiding responsibility for the alleged flights of South Korean drones over the North’s capital, and warned of a "terrible calamity” if they continue. The statement by Kim Yo Jong came a day after North Korea’s Foreign Ministry claimed that South Korean drones carrying anti-North Korean propaganda leaflets were detected in the night skies over Pyongyang on Oct 3, and Wednesday and Thursday this week.

The ministry said North Korean forces will prepare "all means of attack” capable of destroying the southern side of the border and the South Korean military, and respond without warning if South Korean drones are detected in its territory again. South Korea’s defense minister initially denied the accusation, but the South’s military later adjusted its response, saying it couldn’t confirm whether or not the North’s claims were true.

In comments published through state media, Kim, one of her brother’s top foreign policy officials, said that the South Korean military’s vague statements should be taken as proof that it was "either the main culprit or accomplice in this incident.” "If the military stood by while its own citizens employed drones, a widely recognized multi-purpose military tool, to violate another country’s sovereignty, thereby increasing the risk of armed conflict with a potential adversary, this would amount to intentional acquiescence and collusion,” she said.

"The moment a South Korean drone is discovered once again in skies above our capital, a terrible calamity will surely occur. I personally hope that does not happen.” South Korea’s military and government didn’t immediately respond to Kim’s comments.
