Thousands of demonstrators have gathered at Prague's Old Town Square to protest against recently extended government restrictions designed to contain the coronavirus.
According to police estimates, some 2500-3000 people protested in the Czech capital's central square on Sunday.
It comes a day after nine people were arrested in Denmark on Saturday when protests against the country's restrictions became violent in Copenhagen and Aarhus.
Footage of the demonstration in Prague showed many protesters not wearing masks and standing close to one other.
Demonstrators waved Czech flags and posters, some of which read "Stop corona-terror" and "Stop COVID tyranny."
Included in the programme for the demonstration were speeches by business representatives from the hospitality sector, fitness trainers and business unions, among others, CTK agency reported.
Former president Vaclav Klaus was also among the speakers.
"These one-way decrees from the government must stop," Klaus said, as cited by CTK.
"We want to tell the government and say it clearly and unequivocally: enough is enough. There have been enough of all the prohibitions and orders that are fundamentally damaging our lives."
Klaus, 79, also said he will not get inoculated for Covid-19.
On Thursday, the Czech Republic extended its lockdown measures in the fight against the pandemic.
The government's highest coronavirus warning level will initially apply until January 22, and further tightening cannot be ruled out, according to Health Minister Jan Blatny.
A maximum of two people are allowed to meet in public. Shops selling goods not considered daily necessities are shut, as are hotels, restaurants and cultural institutions.
There is a nightly curfew between 9pm and 5am.
Earlier on Sunday, the country's president Milos Zeman called on his compatriots to be patient and follow the measures in place to stem the spread of the virus.
He said the recent increase in cases was due to people who were weary of the restrictions and failed to observe them.
