China suspended flights and trains, cancelled professional basketball league games and announced mass coronavirus testing in Wuhan on Tuesday as widening outbreaks of the delta variant reached the city, reported Saudi Press Agency (SPA).

The cities of Nanjing and Yangzhou have cancelled all domestic flights, and Beijing has halted long-distance trains from 23 stations. The Chinese Basketball Association said that matches of its men's professional league would be suspended because of the pandemic.

Wuhan, a provincial capital of 11 million people in central China, is the latest city to undergo city-wide testing. Three cases were confirmed there on Monday, its first non-imported cases in more than a year, the report said.

They were among 90 new cases confirmed nationwide the previous day, the National Health Commission said Tuesday. Of those, 61 were locally spread ones and 29 among people who had recently arrived from abroad.
