Hong Kong shares end morning sharply lower;
Hong Kong shares ended the Tuesday morning session sharply lower in a free-fall, dragging the benchmark index down 8.04 percent to below the 22,000-point level for the first time since August, as nervous dealers resorted to margin calls to cover sharp losses.
Hong Kong shares opened 0.9 percent lower on Thursday with Asia's largest oil and gas producer PetroChina leading losses, weighed down by lower oil prices amid a firmer US dollar.
