China tightens travel restrictions
China has responded to the spike in Covid cases we mentioned earlier with a dramatic tightening of travel restrictions across the country.
The latest outbreak has so far infected more than 400 people in 25 cities, including the capital city Beijing, reports our correspondent Helen Davidson.
Wuhan, the city at the epicentre of the pandemic more than 18 months ago, has seen its first cases since the virus was eliminated there last year. Mass testing is being carried out in the city.

Nanjing and Yangzhou have since cancelled all domestic flights, while Beijing has suspended 13 rail lines and halted inbound long-distance ticket sales from 23 stations, according to state-run news agency Xinhua.
