Jornal Do Brasilia - Trash balloons from North Korea hit South's presidential compound

It is the first time the South Korean leader's office in downtown Seoul, which is protected by scores of soldiers and a no-fly zone, has been directly hit by any of the thousands of trash-carrying balloons launched by Pyongyang since May.

"The chemical, biological and radiological (warfare) response team has safely collected the trash balloons," the presidential security service told AFP.

"After investigation, results have confirmed that there were no danger or contamination of the object," it said.

South Korea's Joint Chiefs of Staff had earlier confirmed the North was once again sending the trash-carrying balloons, while Seoul city authorities also issued an alert Wednesday morning.

"If you find any fallen balloons do not touch them, and report them to the nearest military unit or police station," it said.

This is the tenth time the North has sent the balloons across the border this year in what it claims is retaliation for anti-regime propaganda balloons launched by South Korean activists.

In response to the waves of balloons, South Korea on Sunday resumed "full scale" propaganda broadcasts from loudspeakers along the border, directed at North.

Seoul has also fully suspended a tension-reducing military deal and restarted live-fire drills on border islands and near the demilitarised zone that divides the Korean peninsula.

The two Koreas remain technically at war because the 1950-53 conflict ended in an armistice, not a peace treaty.

The propaganda broadcasts -- a tactic which dates back to the Korean War -- infuriate Pyongyang, which previously threatened artillery strikes against Seoul's loudspeaker units.
