North Korea has instructed its army to be ready to attack South Korea on Sunday. At the same time, this announcement of North Korea has increased the pressure on South Korea.

North Korea says that South Korea flew drones over its capital Pyongyang. However, South Korea has denied the allegation of sending drones.

South Korea has also warned North Korea that it will give severe punishment if the safety of its citizens is threatened.

North Korea on Friday accused South Korea of ​​launching drones to drop propaganda leaflets over Pyongyang three times this month, and threatened to respond with force if it happened again.

Army got instructions to be ready

North Korea's state news agency KCNA quoted a defence ministry spokesman as saying Pyongyang was seeing the possibility of more drones flying over the capital and its military had been told to prepare for all scenarios, including conflict.

On Friday, North Korea accused South Korea of ​​sending drones into Pyongyang overnight this week and last week and said the intrusions required retaliation.

This warning was given to Seoul

Kim Yo Jong, the powerful sister of North Korean leader Kim Jong Un, warned Seoul on Saturday of a "terrible disaster."

He said the South Korean military was responsible if it failed to identify a drone flown by an NGO crossing the border.

South Korea's Joint Chiefs of Staff said it could not confirm North Korea's allegations.
