Some developments in relations between South and North Korea today.
Kim Jong-un's sister, Kim Yo-jong, who is believed to be Pyeongyang's second in command, has demanded that South Korea stop people from using balloons to send leaflets over the border denouncing the regime.
According to the North's state-run media, she said that if the leaflet campaigns don't stop, then Pyongyang will scrap its military agreement with Seoul.
She also said that the North is prepared to tear down the industrial complex at Gaeseong, which the two sides used to run together, and the liaison office.
In response, South Korea's Unification Ministry said it has already been looking at introducing legislation that would stop the campaigns.
They do need to stop, it said, because they threaten the safety of people who live near the border.
But experts say laws protecting free speech will make it difficult for the government to ban leaflet campaigns outright.
