North Korea has started broadcasting anti-South Korean propaganda messages along their shared border after South Korea began anti-North Korean propaganda messages on Friday, reported South Korea's Yonhap News Agency.

South Korea had declared on 8 January it would restart anti-North Korea propaganda in the demilitarised zone along their shared border after their rival broadcast about successfully testing a Hydrogen bomb. The bomb test had led to a 5.1-magnitude earthquake. 

South Korea had moved its troops away from the border before the broadcasts were started by them, on what is believed to be the birthday of North Korea's leader Kim Jung-un.

Along with criticising North Korea's nuclear move, economy and human rights condition, the broadcasts also included K-pop songs, weather forecast and news. 

There has been global outrage against North Korea's claim that it tested a hydrogen bomb, which is supposed to be more dangerous than an atom bomb.

The United Nations Security Council has vowed to begin work on a draft immediately to take "significant measures" against North Korea.

The US flew reconnaissance planes from the Japan base after North Korea's claim of successful test of its hydrogen bomb.

In August 2015, when South Korea initially began propaganda messages after a 11-year break, gun-firing had taken place between the two sides, reports The Hindu.
