South Korea announced Monday it'll suspend a rapprochement deal with North Korea to punish it over its launches of trash-carrying balloons, even after the North said it would halt its balloon campaign.

Over several days, North Korea flew hundreds of balloons to drop trash and manure on South Korea in an angry reaction against previous South Korean civilian leafleting campaigns. On Sunday, South Korea said it would take "unbearable" retaliatory steps in response, before North Korea abruptly announced it would stop flying balloons across the border.
