Austria has returned to a full national lockdown as protests against new restrictions aimed at curbing Covid-19 infections spread across Europe.
From midnight, Austrians have been asked to work from home and non-essential shops have closed.
New restrictions have sparked protests throughout Europe. People clashed with police in the Netherlands and Belgium.
Infection rates have risen sharply on the continent, prompting warnings from the World Health Organization (WHO).
On Saturday WHO regional director Dr Hans Kluge told the BBC that unless measures were tightened across Europe – such as on vaccines, wearing masks and with Covid passes for venues – half a million more deaths could be recorded by next spring.
Last week Austria became the first European country to make Covid vaccination a legal requirement, with the law due to take effect in February. Politicians in neighboring Germany are debating similar measures as intensive care units there fill up and case numbers hit fresh records.
This is Austria’s fourth national lockdown since the pandemic began.
Authorities have ordered residents to stay home for all but essential reasons, including work, exercise and shopping for food.
Restaurants, bars, hairdressers, theatres and non-essential shops must all close their doors. These measures will continue until 12 December, although officials said they will be reassessed after 10 days.
Speaking on ORF TV on Sunday night, health minister Wolfgang Mueckstein said the government had to “react now”.
“A lockdown, a relatively tough method, a sledgehammer, is the only option to reduce the numbers [of infections] here,” he told the broadcaster.
Tens of thousands of people protested in the capital Vienna ahead of the lockdown. Brandishing national flags and banners reading “Freedom”, protesters shouted “Resistance!” and booed the police.
