China on Saturday mourned the thousands of "martyrs" who have died in the coronavirus outbreak, flying the national flag at half mast across the country and suspending all forms of entertainment.

The day of mourning coincided with the start of the annual Qingming tomb-sweeping festival, when millions of Chinese families pay respects to their ancestors.

At 10 a.m. (0200 GMT) Beijing time, the country observed a three-minute silence to mourn those who died, including frontline medical workers and doctors.

In Zhongnanhai, the seat of political power in Beijing, President Xi Jinping and other Chinese leaders paid silent tribute in front of the national flag, with white flowers pinned to their chest as a mark of mourning, state media reported.
