A North Korean balloon carrying trash fell on the South Korean presidential compound in Seoul on Thursday, marking the second such incident in recent months.
The debris raised concerns about the vulnerability of critical South Korean sites amid ongoing tensions with the North.
The South Korean presidential security service reported that one of the balloons floated from North Korea, burst over the compound, scattering rubbish. Fortunately, no hazardous materials were found.
It remains unclear whether South Korean President Yoon Suk Yeol was present during the incident, though he was scheduled to meet Polish President Andrzej Duda later in the day.
This balloon incident is part of a Cold War-style psychological campaign resumed by North Korea in late May, where trash-filled balloons are sent over the border. A similar occurrence in July resulted in no injuries or dangerous substances.
North Korea claims these actions are in retaliation to South Korean drones allegedly dropping propaganda leaflets over Pyongyang earlier this month.
According to reports, the latest balloon also carried leaflets criticizing President Yoon and his wife, Kim Keon Hee. The leaflets were scattered around the Yongsan district, where the presidential office is located.
There are also concerns that North Korea has begun using GPS technology to improve the accuracy of their balloon drops.
