The death toll from a house explosion Tuesday in southwest China's Yunnan Province rose to five, said local authorities Wednesday.

The blast occurred around 9:50 a.m. in a four-story residential house in the village of Shunhe in Weixin County, leaving one dead and four others missing as of 3:30 p.m. Tuesday, said a spokesman with the publicity department of Weixin County Committee of the Communist Party of China.

The bodies of the four missing were later recovered, bringing the death toll to five, said the spokesman.

An initial investigation showed the accident was triggered by inflammable material. Police are continuing to investigate the incident.
