Around 2000 protesters on Monday turned out in Germany's city of Magdeburg to march against the government's anti-coronavirus measures.
Demonstration marches have been taking place across parts of Germany regularly on Mondays in what participants refer to as "Monday walks".
Magdeburg police, present in large numbers, used their Twitter account to urge people to stay away from the illegal meet which contravenes the current anti-corona measures that ban large gatherings.
Currently no more than 10 people are allowed to meet unless they have special dispensation or have registered the protest and received clearance.
A police press spokesman for Magdeburg, the capital of the eastern state of Saxony Anhalt, said police had started working on establishing the identities of people taking part.
The protests took place after Germany on Friday announced upcoming tighter restrictions for unvaccinated people.
Still to be put into place, restrictions include a booster vaccination or two vaccinations plus a test to be able to take part in much of public life including the hospitality and leisure sector.
Health ministers of the 16 German state were still discussing the possibility of a fourth vaccination and mandatory vaccinations.
Germany's seven-day Covid incidence rate per 100,000 people was at 375 on Monday, according to RKI, with the northern city state of Bremen topping the list with 1,080 cases and southern Germany's Berchtesgadener Land district in Bavaria showing the lowest rate with 111 reported cases.
