China is once again mass testing an entire city for the coronavirus amid a regional outbreak in Xinjiang province.
Around 4.7m people in Kashgar are being tested, with 138 asymptomatic cases found so far. Earlier in October, the city of Qingdao tested its entire population of nine million people.
China has been largely successful in bringing infection rates down, but there continue to be small outbreaks.
Xinjiang is home to China’s mostly-Muslim Uighur minority which rights groups say is being persecuted by the government in Beijing.
Schools in Kashgar have been closed and residents are not allowed to leave the city unless they have a negative test report.
