North Korea on Friday began its anti-South Korea propaganda broadcasts in border areas in response to Seoul's resumption of anti-Pyongyang broadcasts, Yonhap news agency reported.
The North Korea military began anti-South Korea broadcasts in some of its frontline units with loudspeakers, Xinhua cited a statement.
The South Korean military too resumed propaganda broadcasts from noon as planned at 11 locations along the inter-Korean border, installed with a set of large loudspeakers.
The resumption, which Pyongyang had called as a "direct act of declaring war", came in retaliation for what Pyongyang claimed was its first successful test of a "hydrogen bomb" on Wednesday.
