About a million people on the outskirts of Wuhan, the Chinese city where the coronavirus first broke out in December 2019, have been placed under lockdown.
Residents of Jiangxia district have been ordered to stay inside their homes or residential complexes for three days after four asymptomatic cases of Covid were detected, the BBC writes.
In Wuhan, a city of 12 million people, routine testing revealed two asymptomatic cases two days ago.
Two other cases were found through contact tracing and shortly after the blocking order was issued.
China is implementing a strategy of 'zero cases of COVID', including mass testing and strict isolation. Such a measure has resulted in fewer deaths than in many other countries in the world.
Wuhan became known around the world in early 2020 as the first place scientists discovered the new coronavirus and the first city to be put under strict restrictions.
