South Korean authorities have arrested six American nationals caught in the act of sending plastic bottles packed with rice, Bibles, and U.S. dollar bills toward North Korea by sea.
The incident occurred around 1:03 a.m. on Friday off the coast of Ganghwa Island, a border territory northwest of Seoul known for its proximity to North Korea—just 10 kilometers from parts of the maritime boundary.
“We have arrested and are questioning six American nationals in their 20s to 50s on suspicion of violating the Framework Act on the Management of Disasters and Safety,” the head of the Ganghwa Police investigation team told AFP.
“An interpreter was provided as they could not speak Korean, and we have since started the questioning,” the official added.
The group, reportedly acting independently or in connection with activist efforts, was found attempting to release thousands of floating bottles into the sea—an act long used by NGOs and anti-regime groups to deliver outside information and aid to North Koreans.

Ganghwa Island has a history of being used for such missions, with prior launches containing rice, USB drives filled with K-pop music and South Korean dramas, and even currency. However, these acts have grown increasingly sensitive.
Since November, South Korea designated several border regions, including Ganghwa, as danger zones. The government warned that sending materials across the border via bottles or balloons could be considered provocative by the North, escalating tensions between the two Koreas.
Last year, both countries engaged in a bizarre propaganda war. In retaliation for anti-regime leaflets and material launched from the South, North Korea sent thousands of balloons filled with garbage and waste across the border. In response, Seoul reactivated its loudspeaker propaganda broadcasts—blaring K-pop and international news. Pyongyang replied with eerie audio transmissions that unsettled residents near the DMZ.
President Lee Jae-myung, who assumed office earlier this month, has promised a more conciliatory approach to North Korea. One of his first acts was halting the controversial loudspeaker broadcasts. North Korea responded by ending its strange audio transmissions the next day.
However, the arrest of six Americans for acts that could reignite tensions may put Lee’s diplomatic stance to an early test. While South Korea balances national security concerns with human rights activism, the case could spark international attention—particularly from the United States.
As of Friday evening, the American Embassy in Seoul has not issued a formal response, and the identities of the arrested individuals remain undisclosed.
