Shanghai shares continue to plunge. Share prices in Shanghai are continuing their free-fall, with the benchmark index losing more than 8 percent on Monday morning.

Sell orders flooded in from the start of trading, sending the Shanghai Composite Index below 3,300 points for the first time since March.

The sharp drop came after the index lost 11 percent last week despite government efforts to prop up the market.

Market players say growing concerns among investors about a slowdown of the Chinese economy have sparked panic selling.
