SHANGHAI – Hong Kong shares fell on Tuesday amid growing concern over the Omicron COVID-19 variant, while property and tech shares tumbled.

At the close of trade, the Hang Seng index was down 318.63 points, or 1.33 percent, at 23,635.95. The Hang Seng China Enterprises index fell 1.55 percent to 8,418.61.

The property sector dipped 2.77 percent and the mainland's developers sank 6.87 percent.
