Thousands of people demonstrated in the streets of France again against the government's Covid-19 vaccination policies amid concern from rights groups about anti-Semitic sentiment in the protest movement.

Saturday's protests were called for the sixth weekend in a row to denounce a new “health pass” system announced by President Emmanuel Macron that they see as unfairly restricting the rights of the unvaccinated.

Under the system, introduced progressively since mid-July, anyone wishing to enter a restaurant, theatre, cinema, long-distance train, or large shopping centre must show proof of vaccination or a negative test, AFP reports.

Around 200,000 people have marched in previous weekends, according to interior ministry figures, while organisers claim the real number is nearly double that.
