A popular all-female music band in North Korea has disappeared from the North's broadcasts since mid-July, spawning speculation over a possible breakup of the group created three years ago.

The Moranbong Band, dubbed a North Korean girl group, was established in July 2012 by the North's young leader, Kim Jong-un, featuring Western-style music and outfits.

Without clear reasons, the band's members have not appeared on programs aired by the North's Korean Central Television since July 15, with only their music being broadcast, according to an analysis by Yonhap News Agency on Monday, based on TV footage.

Footage such as natural views or streets in Pyongyang has replaced those featuring the band's music performances, it showed.

It is not immediately known why the North's popular music band has disappeared from the public eye.

Without revealing any information about the Moranbong Band, such as a possible breakup, North Korea announced the establishment in late July of a new music band, named the Chongbong Band, which it said is a "promising revolutionary art troupe."

The Chongbong Band, also created by the North's leader, is a light music group consisting of instrumentalists and singers, the Korean Central News Agency said. It made its debut in a joint concert held in Russia on Aug. 31.

Radio Free Asia said last month that the Moranbong Band has been replaced by the Chongbong Band as the former's members got married or some of them were deported from the country. (Yonhap)
