韩国宣布，星期五恢复向朝鲜的高音喇叭宣传广播，以此回应平壤本周早些时候的核试验。
韩国总统府青瓦台的一位官员说，“广播从星期五中午开始”。
1950-53朝鲜半岛冲突后，韩国和朝鲜实际上仍处于战争状态，去年8月两国因高音喇叭广播争端互射炮火。在与平壤就缓和敌对状态达成一揽子措施协议后，韩国停止了广播。
韩国总统国家安全高级官员赵泰永在一份声明中说，朝鲜宣称星期三进行的氢弹试验“严重违反”了8月的协议。
他说：“我们的军队严阵以待，如果朝鲜发起挑衅，将予以严厉惩罚”。
South Korea announced it will resume loudspeaker propaganda broadcasts into North Korea on Friday in response to Pyongyang’s nuclear test earlier this week.
“The broadcasts will begin tomorrow at noon (0300 GMT),” an official at the presidential Blue House said.
The two countries, which remain technically at war after the 1950-1953 Korean conflict, traded artillery fire in August over the broadcasts. South Korea stopped the transmissions after it agreed with Pyongyang on a package of measures aimed at easing animosities.
The North’s claim that it tested a hydrogen bomb Wednesday is a “grave violation” of that August agreement, Cho Tae-yong, a senior presidential national security official, said in a statement.
“Our military is at a state of full readiness, and if North Korea wages provocation, there will be firm punishment,” Cho said.
