An all-female North Korean pop band formed by leader Kim Jong Un abruptly cancelled a Beijing concert on Saturday and headed back home to Pyongyang, Chinese media and the concert venue said.

The Moranbong Band was visiting China along with North Korea's State Merited Chorus and was due to perform later on Saturday at Beijing's National Centre for the Performing Arts.

The band is Kim's pet project as he tries to put his own personal stamp on the North Korean arts, and the short haircuts of the group's young women members are trend-setting in the capital Pyongyang.
