North Korea threatens South with revenge over leaflet campaign

North Korea threatened to take revenge on South Korea in retaliation for a leafletting campaign along the border, in a statement made by Kim Yo Jong, North Korean leader Kim Jong Un's sister.
 "The right to taking the next action against the enemy will be entrusted to the General Staff of our army," she said. She did not provide details about the form any future measures could take. "By exercising my power authorized by the Supreme Leader, our Party and the state, I gave an instruction to the arms of the department in charge of the affairs with enemy to decisively carry out the next action," she said.
 North Korea has already threatened to close a liaison office and to pull out of a military agreement with the South in 2018, and has since cut off communications with the South. At the time, the statement also came from Kim Yo Jong.
Pyongyang is demanding that Seoul take action against activists who allegedly sent some 50,000 leaflets into the reclusive neighbouring nation criticizing the North Korean leader. Such campaigns have generally sought to encourage North Koreans to topple the government.
North Korea has threatened military action and accuses Seoul of having done nothing to address the campaign.
