The mayor of Ukraine's capital Kiev, Vitali Klitschko, imposed new coronavirus restrictions as the country struggles to contain a surge in infections.

Ukraine reported 26,071 new Covid cases in 24 hours on Thursday — a record for the ex-Soviet country since the pandemic began.

Kiev schools will work remotely when they resume classes after a holiday break on Monday, Mayor Klitschko announced at a last-minute press conference.

He also imposed restrictions on the city's public transport system, saying vaccination certificates or negative tests will be required to use the network.
