Officials from South Korea's Gyeonggi Province visited the house of a North Korean defector-activist on Wednesday and alerted him of a new administrative order banning high-pressure gas normally used to fuel balloon launches.

The administrative order — which is Gyeonggi Province’s first case of formally prohibiting activists from sending propaganda leaflets to North Korea — also includes an entry ban into several designated “danger zones” and the total prohibition on the preparation, transportation and scattering of leaflets in the area.
