Glasgow's lockdown is being tightened after coronavirus cases skyrocketed in the city.
Restrictions on visiting other households are being reintroduced in the city, First Minister Nicola Sturgeon announced on Tuesday.
The restrictions will apply to people living in Glasgow, West Dunbartonshire and East Renfrewshire – affecting more than 800,000 people.
They will be in place for two weeks but will be reviewed after a week.
The move came after 66 new positive tests were recorded in the Greater Glasgow and Clyde area.
The daily incidence rate of Covid-19 is now almost 33 new cases per 100,000 people in West Dunbartonshire, 22 in Glasgow and almost 19 in East Renfrewshire.
The rate for the rest of Scotland is just over 10.
Ms Sturgeon said the virus seemed to be spreading inside homes and between households in the three affected areas and residents should no longer host members of other households in their homes.
On Monday the First Minister expressed concern after 160 more people tested positive for coronavirus in Scotland.
She said the rise in cases was "partly the result of a greater number of people being tested", but added the news was "undoubtedly a concern".
Any connection between cases was being "carefully considered" by health protection teams, she said.
Scotland has seen a total of 20,478 cases of Covid-19 and 2,494 people have died since the pandemic began.
The country has been easing its lockdown restrictions in recent weeks, with pubs, gyms and swimming pools reopening.
"As we release ourselves from lockdown, we release the virus from lockdown too," Ms Sturgeon warned.
"Please follow the guidance – that's the only way we can make sure these re-openings can happen safely, and they don't spark an increase in transmission that could take us all back again.
"The figures demonstrate very clearly that this virus is still present across the country.
"The clusters we have seen show it will spread very rapidly if it gets the chance, and the admissions to intensive care last week remind us that the virus is still immensely dangerous for some people."
