British Prime Minister Boris Johnson has warned there are signs of a "second wave" of coronavirus in Europe, as he defended a 14-day quarantine on travellers from Spain, reports BBC.
The British PM said the government had to be "swift" - and it would continue to take further action "where it is necessary".
It comes after the Spanish Prime Minister Pedro Sánchez called the UK's decision to change the rules for Spain "unjust".
Pedro Sánchez said tourists in most regions in Spain would be safer from coronavirus than in the UK.
The UK is advising against all non-essential travel to Spain, including the Balearic and Canary Islands. It also removed Spain and its islands from the list of countries that are exempt from the 14-day quarantine rule.
Meanwhile, Germany has advised against travel to three areas of Spain.
Speaking during a visit to Nottinghamshire, Johnson said: "What we have to do is take swift and decisive action where we think that the risks are starting to bubble up again.
"Let's be absolutely clear about what's happening in Europe, amongst some of our European friends, I'm afraid you are starting to see in some places the signs of a second wave of the pandemic."
It came as the UK reported a further 119 coronavirus deaths - taking the official number of deaths so far to 45,878 - but the daily figure is typically higher on Tuesdays due to delays in reporting deaths at the weekend.
An additional 581 positive cases have also been reported across the UK, a small dip on recent days.
