Trash-carrying balloons sent by North Korea hit the South Korean presidential compound Wednesday, security officials told AFP, prompting Seoul to mobilise chemical response teams in the escalating tit-for-tat propaganda war.
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.
