Covid-19: Europeans urged to wear masks for family Christmas
The World Health Organization (WHO) has urged Europeans to wear masks during family gatherings at Christmas.
It said Europe was at "high risk" of a new wave of coronavirus infections in the early part of 2021, as transmission of the virus remained high.
Countries across the continent have been registering thousands of daily cases and hundreds of deaths.
Germany was among countries tightening restrictions on Wednesday, closing schools and non-essential businesses.
Meanwhile European Commission President Ursula von der Leyen said the first Covid vaccine would be authorised for use within a week.
Ms von der Leyen told the European Parliament the Pfizer/BioNTech vaccine - developed in Germany - would be rolled out for the bloc immediately, more than a week earlier than originally envisaged.
What does the WHO say?
A statement from the WHO's European regional office said that the massive increase in gatherings of families and friends across Europe during the winter holiday season brought a significant risk of increased Covid-19 transmission.
It urged individuals, families and communities to play their part to prevent another resurgence of cases.
Family gatherings should be held outside if possible, and if indoors participants should wear masks and practice social distancing, it said.
