After conflicting headlines over his death - and discussions of his successor - South Korea's state-owned news agency Yonhap has reported that North Korean leader Kim Jong Un has made an appearance at a factory after a 20-day absence.

The North Korean dictator is reported to have he attended a completion ceremony at a fertilizer factory in Sunchon, a city in South Pyongan Province, according to Yonhap.

This marks his first reported public activity since he was last seen on April 11, presiding over a political bureau meeting of the ruling Workers Party. His apparent absence in events commemorating the 108th birthday of late founder and his grandfather, Kim Il-sung, on April 15 spawned speculation about his health.

Additionally, the Korean Central News Agency said, Kim "attended the ceremony" on Friday and "all the participants broke into thunderous cheers of 'hurrah!'" when he appeared.
