Beijing shifted more classes online Thursday in a further tightening of COVID-19 restrictions, as China’s capital seeks to prevent a wider outbreak.

Shanghai city authorities said Wednesday they will analyse the results of new rounds of testing to determine which neighbourhoods can safely expand freedom of movement for residents.
