North Korea launched more trash-filled balloons toward Seoul early Friday morning, the second barrage since South Korea showed off its biggest weapons at a military parade earlier this week.

“North Korea is suspected of launching anti-ROK trash balloons once again. Based on current wind patterns, there is a possibility these could drift toward northern Gyeonggi Province and the greater Seoul metropolitan area,” Seoul’s Joint Chiefs of Staff (JCS) stated at around 2:30 a.m. on Friday.
