Pyongyang expands propaganda broadcasts in border areas, says Seoul

North Korea has expanded propaganda broadcasts in border areas in response to South Korea's resumption of such broadcasts, a Seoul official said on Monday.

Pyongyang seemed to have expanded broadcasts to all of 11 locations where Seoul's military restarted transmitting propaganda messages over loudspeakers along the border, Xinhua news agency reported, quoting an unnamed government official.

Seoul forces resumed the psychological warfare on Friday, two days after Pyongyang said it had successfully tested its first hydrogen bomb.

On the same day, North Korea forces reportedly restarted propaganda broadcasts in two sites in response.

South Korea's Defence Ministry spokesman Kim Min-Seok told a press briefing Monday that North Korea forces are airing propaganda messages from loudspeakers in frontline areas, without elaborating on details.

North Korea broadcasts reportedly involve music praising top leader Kim Jong-un and its regime, and messages denouncing South Korean President Park Geun-hye.

The South Korean broadcasts include the criticism of Kim Jong-un and his regime as well as recent pop music, world news and weather forecasts.
