Europe on Sunday night faced an increasingly violent backlash against new Covid restrictions imposed to deal with a record number of new cases on the Continent.
Riot police were forced to use water cannons and tear gas as peaceful demonstrations turned violent in Brussels when tens of thousands of protestersmarched through the streets against the measures.
They smashed the glass at the entrance to a European Commission building after young men in hoods attacked police vans with baseball bats.
It followed a second night of disorder in the Netherlands on Saturday over the introduction of new coronavirus restrictions, where police opened fire on the crowds, wounding at least four people.
Demonstrations also took place in Austria, Italy, Croatia, Denmark and Switzerland over the weekend amid clampdowns on civil liberties by European governments to curb a steep increase in the number of infections that are putting healthcare systems under strain.

On Sunday, Austria's interior minister warned of increasing "radicalisation" among the population, days after it was announced that three anti-lockdown protesters had been arrested for setting a police car on fire in an attempt to burn an officer.
Europe is experiencing a worrying spike in the number of coronavirus cases. On Sunday, France reported some 19,749 new infections, a 58 per cent jump from a week ago. Gabriel Attal, a government spokesman, told reporters that the "fifth wave is starting at lightning speed".
The unrest increased debates in Germany and other European countries about the possible introduction of compulsory immunisations, with low vaccination rates prompting fears a new wave of infections could once again cripple the Continent.
As Europe endured fresh violence, in Britain, Sajid Javid insisted that no such measures were necessary, saying he hoped that people can "look forward to Christmas together".
The Health Secretary played down the likelihood of tougher curbs being introduced in England despite cases surging on the Continent.
Javid said the "one big difference" between Britain and parts of Europe where coronavirus is soaring is the UK's vaccine booster programme.
"It's the most successful of Europe," he told BBC One's Andrew Marr Show on Sunday, adding it is "absolutely key for us to keep this virus at bay".
The UK has completed 15 million booster doses, with 25 per cent of over-12s covered.
He also highlighted that the UK "made a tough decision back at the start of the summer" to open up, while "other countries didn't follow our course".
Despite Javid's upbeat tone, he warned that the public must "remain cautious, not complacent in any way", describing the virus as "very unpredictable".
He also stressed that taking up the flu vaccine was "just as important this winter" as receiving a Covid booster shot, in order to prevent the NHS from being overwhelmed.
A government source echoed his sentiments on Sunday night, telling The Telegraph: "The current data shows no sign of a need to change course. Whilst we always remain vigilant, Plan A is working. But the most important way to minimise risk against the virus is to come forward for a booster jab when called."

The Health Secretary vowed earlier in the day that Britain will not consider making vaccines mandatory for the general population.
In Brussels, police arrested 44 people on Sunday, while three officers and one demonstrator were hospitalised after the violence.
Police were forced to use bulldozers to remove blockades on city streets made from wooden pallets and set on fire.
Several of the demonstrators caught up in the clash carried Flemish nationalist flags, while others wore Nazi-era yellow stars.
The stand-off with riot police took place throughout the Belgian capital's EU and government district, just metres from the prime minister's residence, the US and Russian embassies.
Austria will introduce a brutal national lockdown on Monday, with other European nations set to bring in similar restrictions in the coming days.
In Greece, unvaccinated people will be banned from indoor venues, including restaurants, cinemas, museums and gyms.
In Slovakia, Eduard Heger, the country's prime minister, announced a "lockdown for the unvaccinated".
With infections hitting a record high for a 14th consecutive day, German politicians are also debating forcing all citizens to get vaccinated, with several members of Angela Merkel's conservative bloc on Sunday pushing for the measure.
However, key figures in the Social Democratic Party (SPD), which is set to lead the next government, have said compulsory vaccinations are unnecessary and "constitutionally problematic".
The current caretaker government led by Merkel would not be able to bring in a vaccine mandate without the support of the SPD, which is currently a junior coalition partner.
