The latest from across Europe
- Portugal's government is set to announce tough restrictions starting tomorrow that will go on for at least a month. Under the lockdown due to be agreed by ministers today, people will be told to stay at home but primary schools children will still go to school. Portuguese will, however, be allowed to go and vote in presidential elections this month. President Marcelo Rebelo de Sousa is campaigning for reelection - he was initially given a positive Covid test earlier this week, but has now been told he's negative.
- German Health Minister Jens Spahn has appealed to all bosses to allow working from home. He says Germans are moving around more than they were during the first lockdown and, on a day that more than 1,000 further deaths have been announced, he says social contacts will have to be reduced over the next two to three months.
- Italy's government is facing crisis, after Prime Minister Giuseppe Conte's cabinet backed a plan on how to spend €222.9bn (£200bn) in EU Covid recovery funds. Ex-PM Matteo Renzi is considering whether to pull his ministers out of the government because he fears the money will be squandered.
- Albania’s government is refusing to divulge the source of coronavirus vaccines that have arrived in the country. PM Edi Rama was among the first people to be vaccinated on Monday - and says an EU country donated 1,000 doses on condition it was not identified.
Mexico registers record daily death tollHealth officials in Mexico say 1,314 Covid-related deaths were registered on Tuesday. It's the highest figures since the start of the pandemic.
Mexico is the country with the fourth-highest number of deaths worldwide, after the US, Brazil and India.
The country has begun a vaccination drive but with more than 127m inhabitants, health officials say they are facing a mammoth task.
On Tuesday, almost 440,000 doses of the Pfizer-BioNTech vaccine arrived in Mexico City - the fifth shipment so far - and will now be distributed to 25 Mexican states.
Health officials there are also expected to decide this week on whether to authorise Russia's Sputnik V vaccine. The government said that if Sputnik V is authorised it would plan to buy 24 million doses.
UK government considers 24-hour vaccine pilotAdam Fleming - Chief political correspondent
The Department of Health and Social Care is considering a pilot scheme to offer Covid vaccinations 24 hours a day at some locations in the UK.
This would be aimed at NHS workers who do night shifts or other shift patterns rather than the general public.

‘The guilt is just too much’: NHS workers on intensive care traumaSima Kotecha - BBC News
More now on one of the top stories in the UK this morning – that many hospital staff treating the sickest patients during the first wave of the pandemic were left traumatised by the experience.
That's according to a study by King's College London, which found nearly half of the 709 intensive care workers that took part reported symptoms of severe anxiety, depression, post-traumatic stress disorder or problem drinking, as the first wave eased.
One in seven had thoughts of self-harming or being "better off dead". Just over half reported good well-being.
Nursing staff were more likely to report feelings of distress than doctors or other clinical staff in the anonymous web-based survey, which was carried out in June and July last year.
Victoria Sullivan, an intensive care nurse at Queen's Hospital in Romford, said she often can't sleep because she's thinking about what is happening at the hospital.
Her worst moment was breaking the news of a death on the phone, she said, adding that the screams from the patient's relatives "will honestly stay with me forever".
"Telling someone over the phone and all you can say is 'I'm really sorry', whilst they're crying their heart out, is quite traumatising," she said.
"Although you're saying how sorry you are, in the back of your mind, you're also thinking: 'I've got three other patients I've got to go and see, the infusions need drawing up, and meds need to be given and a nurse needs support'.
"The guilt is just too much."
