Sardinia moves back to yellow zone as Alto Adige imposes three-week lockdown.

Alto Adige in northern Italy will be put under a lockdown from 8 February amid high numbers of covid-19 cases, including the first detected case of the new UK variant of the virus, reports Italian news agency ANSA.

The autonomous province has placed itself under a three-week lockdown, with effect from today.

• Italy's covid-19 death toll exceeds 90,000

The measures announced by local authorities include the closure of shops, bars and restaurants, distance learning in schools, a ban on travel between towns - unless for urgent or necessary reasons - and an obligation to wear FFP2 masks.

The move comes into force the same day that Sardinia moves back to a lower-risk yellow zone, joining much of the rest of Italy.
