North Korean leader Kim Jong-un attended a fertiliser factory completion ceremony, state media reported on Saturday, his first public appearance after 20 days of absence that sparked rumours about his health.

North Korea's official Korean Central News Agency (KCNA) reported that Kim cut the tape at the ceremony marking the completion of Sunchon Phosphatic Fertilizer Factory in Sunchon, north of Pyongyang, on Friday. Photos released by KCNA showed Kim, dressed in a dark Mao suit, cutting the red ribbon during the ceremony and talking to accompanying officials with a smile on his face.
