Fresh unrest has erupted in the Netherlands against new lockdown rules amid rising Covid-19 cases in Europe.
People hurled fireworks at police and set fire to bicycles in The Hague, one night after protests in Rotterdam turned violent and police fired shots.
Thousands of demonstrators also took to the streets in Austria, Croatia and Italy as anger mounted over new curbs.
Its regional director, Dr Hans Kluge, told the BBC that unless measures were tightened across Europe, half a million more deaths could be recorded by next spring.
“Covid-19 has become once again the number one cause of mortality in our region,” he said, adding “we know what needs to be done” in order to fight the virus – such as getting vaccinated, wearing masks, and using Covid passes.
Many governments across the continent are bringing in new restrictions to try to tackle rising infections. A number of countries have recently reported record-high daily case numbers. In the Netherlands officials have announced an emergency order in the city, and at least seven people were arrested.
