In Europe, thousands of people protested France's special virus pass by marching through Paris and othercities on Saturday. Most demonstrations were peaceful,but some protesters in Paris clashed with riot police, who fired tear gas.

Some 3,000 security forces deployed around the French capital for a third weekend of protests against the pass, whichwill be needed soon to enter restaurants and other places. Police took up posts along the city's Champs-lysesto guard against an invasion of the famed avenue.

With virus infections spiking and hospitalizations rising, French lawmakers have passed a bill requiring the pass in most places as of Aug. 9. Polls show a majority of French support the pass, but some are adamantly opposed. The pass requires a vaccination or a quick negative test or proof of a recent recovery from COVID-19 and mandates vaccine shots for all health-care workers by mid-September.

Tensions flared in front of the famed Moulin Rouge nightclub in northern Paris during what appeared to be the largest demonstration. Lines of police faced down protesters in up-close confrontations during the march. Police used their fists on several occasions.

As marchers headed eastward and some pelted officerswith objects, police fired tear gas into the crowds, plumes of smoke filling the sky. A male protester was seen with a bleeding head, and a police officer was carried away by colleagues. Three officers were injured, the French mediaquoted police as saying. Police, again responding to rowdy crowds, also turned a water cannon on protesters as the march ended at the Bastille.

A calmer march was led by the former top lieutenant of far-right leader Marine Le Pen who left to form his own small anti-European Unionparty. But Florian Philippot's new cause, against the virus pass, seems far more popular. His contingent of hundreds marched on Saturday to the Health Ministry.

Among those not present this week was Franois Asselineau, leader of another tiny anti-EU party, the Popular Republican Union, and an ardent campaigner against the health pass, who came down with COVID-19. In a video on his party's website, Asselineau, who was not hospitalized, called on people to denounce the "absurd, unjust and totally liberty-killing" health pass.

French authorities are implementing the health pass because the highly contagious delta variant is making strong inroads. More than 24,000 new daily cases were confirmed Friday night compared withjust a few thousand cases a day at the start of the month.

The government announcement that the health pass would take effect on Aug. 9 has driven many unvaccinated French to sign up for inoculations so their social lives won't get shut down during the summer holiday season. Vaccinations are now available at a wide variety of places, including some beaches. More than 52 per centof the French population has been vaccinated.

About 112,000 people have died of the virus in France since the start of the pandemic.
