Trash carried by a North Korean balloon fell on the presidential compound in central Seoul on Thursday, officials said, the second such case in recent months that raise concerns about the vulnerability of key South Korean sites during potential North Korean aggression.

The incident comes after the rival Koreas ramped up threats and rhetoric against each other over North Korea's claims that South Korea flew drones over its capital Pyongyang to scatter propaganda leaflets this month.

South Korea's presidential security service said in a statement that one of the balloons floated by North Korea burst over the South Korean presidential compound on Thursday morning, dropping rubbish on the ground. No dangerous items were found.

North Korea has sent trash-carrying balloons into South Korea since late May in a resumption of a Cold War-style psychological campaign. The trash that fell on the South Korean presidential compound in July contained no dangerous material and no one was hurt.

It wasn't immediately known whether South Korean President Yoon Suk Yeol was at the compound during the latest incident. His schedule showed he was due to meet with visiting Polish President Andrzej Duda at his office later Thursday.

South Korea's Dong-A Ilbo newspaper reported earlier Thursday on its website that North Korea's latest balloons contained propaganda leaflets criticizing Yoon and his wife Kim Keon Hee along with trash.

The newspapers said the leaflets were scattered in areas in Seoul's Yongsan district, where Yoon's presidential office is located, and noted that North Korea has recently begun using GPS technology to drop balloons more accurately in intended locations.
