Seoul’s Joint Chiefs of Staff said the North was “launching (suspected) trash balloons aimed at the South once again,” adding they were currently floating across the border, AFP reported.
“Citizens are advised to be cautious of falling debris. If you find any fallen balloons do not touch them and report them to the nearest military unit or police station,” it added.
Seoul city authorities issued an alert to residents Thursday, saying “a suspected balloon from North Korea is confirmed to have entered the airspace of Northern Gyeonggi province. Citizens should be cautious of outside activities.”
This is the eighth round of trash-carrying balloons launched by Pyongyang since late May.
The nuclear-armed North has already sent more than a thousand of the balloons south, calling it retaliation for ones carrying propaganda floated northwards by activists south of the border.
In response to the trash balloons, Seoul has fully suspended a tension-reducing military deal and restarted some propaganda broadcasts from loudspeakers along the border.
It has also carried out live-fire drills in some border areas.
The powerful sister of North Korean leader Kim Jong Un said last week that more “dirty leaflets” from South Korean “scum” had been found in the North’s territory along the border, warning they would pay “a very high price.”
Kim Yo Jong went on to say that North Korean military personnel were “now making an all-out search, throwing into fire and disposing of the found rubbishes,” according to a statement from the official Korean Central News Agency.
