More than 10 people have died in China's commercial hub Shanghai, a local health official says, as the city grapples with its highest temperatures in at least 140 years.
Much of China is in the grip of a summer heatwave, and the China Meteorological Association issued a high temperature warning for several eastern and central provinces, saying temperatures could reach 41C on Wednesday.
Leng Guangming, a spokesman at the Shanghai Municipal Centre for Disease Control and Prevention, said there had been at least 10 victims of heat stroke up to last Friday in the city. He declined to give a more precise or more recent number.

Experts blame a subtropical high pressure system and a lack of rain for the record-breaking heatwave, according to state media.
