SEOUL, SOUTH KOREA -- North Korea flew more balloons likely carrying trash toward South Korea on Wednesday, some of which reportedly fell on the compound of the South's presidential office.
The launches came days after South Korea boosted its front-line broadcasts of K-pop songs and propaganda messages across the rivals' heavily armed border. Their tit-for-tat Cold War-style campaigns are inflaming tensions on the Korean Peninsula, with the rivals threatening stronger steps and warning of grave consequences.
South Korea's Joint Chiefs of Staff said in a statement the North Korean balloons were flying north of Seoul on Wednesday morning after crossing the border. It urged people to be alert for falling objects.
Later in the morning, South Korean media reported that some of the North Korean balloons fell on the compound of the South Korean presidential office and Defence Ministry. The reports said that authorities collected the balloons after finding they carried no dangerous items.
It was North Korea's 10th such launch since late May. The more than 2,000 huge balloons so far have dropped wastepaper, scraps of cloth, cigarette butts and even manure on South Korea. North Korea has said it was responding to South Korean activists scattering political leaflets across the border via their own balloons.
Experts say North Korea considers South Korean civilian leafleting activities a major threat to its efforts to stop the inflow of foreign news and maintain its authoritarian rule. In furious responses to past South Korean leafletting, North Korea destroyed an empty South Korean-built liaison office in its territory in 2020 and fired at incoming balloons in 2014.
The North's balloons haven't caused major damage but have raised security jitters among people worried North Korea could use such balloons to drop more hazardous materials like chemical and biological agents.
South Korea said Sunday it was ramping up its anti-Pyongyang propaganda broadcasts from its loudspeakers at all major sites along the land border because North Korea was continuing launches of trash-carrying balloons. South Korea last Thursday restarted its loudspeaker broadcasts for the first time in about 40 days in retaliation for North Korea's previous balloon activities.
Observers say South Korean propaganda broadcasts can demoralize front-line North Korean troops and residents. In 2015, North Korea fired artillery rounds across the border in anger over South Korea's restart of propaganda broadcasts, prompting the South to return fire.
South Korean Joint Chiefs of Staff spokesperson Lee Sung Joon said the ongoing South Korean broadcasts include K-pop songs and news on South Korean economic development. South Korean media reported the broadcasts also contained news on the recent defection of a senior North Korean diplomat and called the mine-planting work by North Korean soldiers at the border "hellish, slave-like lives."

South Korea has an estimated 40 loudspeakers -- 24 stationary and 16 mobile ones. South Korea's military said Monday it was fully operating the fixed loudspeakers and plans to use the mobile loudspeakers as well.
South Korea's military has warned of other unspecified stronger steps if North Korea continues its balloon campaigns. North Korea hasn't made an official response to the South Korean propaganda broadcasts. But last week, Kim Yo Jong, the powerful sister of North Korean leader Kim Jong Un, threatened new countermeasures against South Korean civilian leafleting as she warned that South Korean "scum" must be ready to pay "a gruesome and dear price" over their actions.
