Beijing: At least four people were killed and ten others injured in separate explosions that rocked a musical instrument factory and a residential building in China, authorities said on Sunday.
The explosion in the musical instrument factory in south China`s Guangdong Province, which took place last night, left three people dead and six others injured.
The factory, located in an industrial park in Lishui Township of Foshan City, mainly produced musical instrument cases, a statement issued by the local government said.
Two people were killed on the spot and one died in hospital later.
The explosion triggered a fire in the building which was extinguished by fire-engines.
The cause of the explosion is being investigated.
In the second incident, one person was killed and four others received minor injuries after an explosion rocked a residential building in tourist city of Xi`an, capital of northwest China`s Shaanxi province, today.
The accident took place in an apartment on the 13th floor of a 24-storey building in the Chunxiaoxinyuan residential area.
Witnesses said a man fell to his death from the building during the explosion, and several neighbouring apartments on the same floor were also severely damaged.
The building has been evacuated and the four injured are being treated in hospital.
A preliminary investigation shows that the accident was triggered by improper use of natural gas, police said.
A comprehensive safety check on the building`s facilities is being carried out, state-run Xinhua news agency reported.
