A group run by North Korean defectors working to promote human rights in the isolated country said it has sent propaganda leaflets including photos of incoming South Korean President Yoon Suk-yeol and aid parcels into the North.
North Korean defectors and activists in South Korea had for decades flown balloons carrying leaflets and humanitarian aid across the heavily fortified border.
Their campaigns were banned by the outgoing Moon Jae-in government which sought to improve inter-Korean ties, but an official whom Yoon nominated to oversee North Korea affairs has said he opposed that ban.
