The Belgian city of Ghent has struggled to persuade its large student population to stick to social distancing rules during the pandemic, but the authorities hope they have found a solution at least to keep outside gatherings under control.
The city, home to some 80,000 students, has painted 100 large, white circles on the ground in St Peter's Square at the heart of the student district, and in nearby parks over the past month, an effort reinforced after partying there last week led to clashes with police.

Ghent mayor Mathias De Clercq said the students themselves had come up with the idea, but stressed that, while Belgian COVID rules limit groups meeting outdoors to four people, it was not mandatory for a group to sit in a circle.
"Everyone is free to use them or not," he told Reuters television. "It's a nice example of nudging, a gentle push towards good behaviour."
Frequently Asked Questions
A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.
There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.
Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
The circles are 6 metres (19 feet 8 inches) in diameter and 4 metres apart.
Students seemed reasonably content with the system as they sat out in the sunshine this week.
"In these harsh times, it's not very easy to meet people and to socialise with your friends. So I think it's a good solution. It looks a little bit weird, but it's effective," said 20-year-old engineering student Elian Colpaert.
Law student Kato Pion said some had complained the authorities were treating them like infants, but thought the circles were a good idea.
"But I think it is actually good that we are given the freedom to sit on the square, of course according to the rules," she said.
