Real Madrid will likely be without coach Carlo Ancelotti for the first leg of the Champions League quarterfinals against Chelsea because of COVID-19.

Patrice Abela first knew something was wrong when his eldest daughter was learning to walk and her feet left trails of blood behind her, yet she showed no sign of distress.

The COVID-19 outbreak in China's largest metropolis of Shanghai remains "extremely grim" amid an ongoing lockdown confining around 26 million people to their homes, a city official said Tuesday.

Shanghai was conducting a mass testing of its 25 million residents Monday as what was announced as a two-phase lockdown entered its second week. Most of eastern Shanghai, which was supposed to re-open last Friday, remained locked down along with the western half of the city.

About 16 million residents in Shanghai are being tested for the coronavirus during the second stage of the lockdown that shifted Friday to the western half of China's biggest city and financial capital.

Meanwhile, residents of Shanghai's eastern districts who were supposed to be released from four days of isolation have been told their lockdowns could be extended if COVID-19 cases are found in their residential compounds.

The city of Shanghai prepared Thursday to reopen its eastern half and shut its western half, while authorities elsewhere announced the lifting of a citywide lockdown in the province hit hardest by China's ongoing omicron-driven coronavirus outbreak.

Residents of the city of Jilin will be able to move about freely starting Friday for the first time in more than three weeks, state broadcaster CCTV said, citing a notice issued by the city.
