Park Sang-hak, a high-profile defector-activist, claimed on Thursday that he flew around 1 million anti-DPRK leaflets with president-elect Yoon Suk-yeol’s face on them in the direction of North Korea earlier this week, the latest challenge to a controversial law that bans such activities.

Park is currently standing trial for charges of launching such balloons with anti-regime leaflets and U.S. dollar bills across the Demilitarized Zone towards the DPRK a year ago in Gyeonggi and Gangwon provinces of South Korea, after Seoul passed an anti-leafleting law in late 2020.
