A Chinese passenger plane with 166 people on board made an emergency landing with two wheels missing at Shenzhen airport on Tuesday, after the pilots aborted landing at nearby Macau and declared "Mayday", aviation authorities said.

The flight, which had taken off from Beijing, was operated by Capital Airlines, the Civil Aviation Administration of China (CAAC) said in a statement. Capital Airlines is a unit of Hainan Airlines. The crew also reported a fault in one of the Airbus A320's engines, according to CAAC.
