The Chinese stock market has suffered its worst day of trading in 10 years after a large wave of share selling by leading investors.
The benchmark Shanghai Composite Index fell nearly 9%, its worst daily performance since February 1997.
The fall comes amid rumours of a crackdown on illegal share offerings and trading, as well as fears about accelerating inflation.
The drop triggered falls in other markets across Asia and Europe.
In Hong Kong the Hang Seng index closed down 1.8%, while in Japan the Nikkei 225 index slid 0.5%.
Markets in London, Frankfurt and Paris also opened sharply down with leading mining stocks - whose performance is influenced by the state of the Chinese economy - under pressure.
