Hong Kong stocks extended their losses for the week on Tuesday, in line with a retreat across Asia as geopolitical worries add to fears the Federal Reserve might not cut interest rates as much as hoped this year.

The Hang Seng Index tumbled 2.16 percent, or 350.41 points, to 15,865.92.

The Shanghai Composite Index rose 0.27 percent, or 7.70 points, to 2,893.99, and the Shenzhen Composite Index on China's second exchange was flat, inching down 0.56 points to 1,743.02. (AFP)
