Thousands took to the streets across Europe and Australia on Saturday to protest fresh rounds of COVID restrictions.
Several countries have recently reintroduced tighter measures in a bid to combat a resurgent wave of infections.
Austria on Friday announced a nationwide partial lockdown — the most dramatic restrictions in Western Europe for months.
Other nations on the continent have resorted to less severe restrictions, often choosing to ban unvaccinated people from venues like restaurants and bars.
The Netherlands
In the Netherlands, rioters threw stones and fireworks at police, and set fire to bicycles as protests against coronavirus curbs turned violent for a second night in the country.
A day earlier, at least two people were injured after police fired shots at protesters and 51 were arrested at an anti-coronavirus restrictions demonstration in the city of Rotterdam.
Police arrested at least one person during a protest in The Hague.
Earlier in the day, several thousand protesters angered at the latest measures gathered in Amsterdam on Saturday. One group earlier in the day had cancelled their rally because of the previous night's violence.
In the southern city of Breda, near the Belgian border, a musical protest called by local DJs against current COVID-19 measures, which include the 8 p.m. (1900 UTC) closure of bars, restaurants and clubs, attracted a few hundred people.
The Netherlands went back into Western Europe's first partial lockdown of the winter last Saturday with at least three weeks of curbs. It is now planning to ban unvaccinated people from entering some venues.
Austria
Around 35,000 protesters, many from far-right groups, marched through the Austrian capital Vienna on Saturday.
Among those protesting were members of far-right and extreme-right parties and groups, including the far-right Freedom Party, the anti-vaccine MFG party and the extreme-right Identitarians.
Police said around 1,300 officers were on duty and several protesters were detained, but didn't give specific numbers.
From Monday, 8.9 million Austrians will not be allowed to leave home except to go to work, shop for essentials and exercise. The restrictions will initially last 20 days with an evaluation after 10 days.
The government is making vaccination against COVID-19 mandatory in the country from February 1 next year.
Northern Ireland
In Northern Ireland, several hundred people opposed to vaccine passports protested outside the city hall in Belfast.
The government of Northern Ireland voted this week to introduce vaccine certificates for admission to nightclubs, bars and restaurants starting December 13.
Some protesters carried signs that have been widely criticized as offensive, comparing coronavirus restrictions to the actions of Nazi Germany.
Croatia
In Croatia, thousands gathered in the capital of Zagreb. Some carried flags, nationalist and religious symbols, along with banners against vaccination and what they describe as restrictions of people's freedoms.
