Extension of the measures in force, implementation of new restrictions, or a vaccination campaign: the reasons for the discontent were numerous.
This weekend, rallies were held in several countries around the world, to protest against health measures to try to stem the Covid-19 epidemic.
In Ireland, 23 people were arrested Saturday in Dublin during an anti-containment protest, which resulted in violence and was condemned by Prime Minister Micheal Martin.
Among the demonstrators, who distributed leaflets with the slogan "Let Ireland live" and chanted "end the confinement", some wore clothes with the logo of the National Party, Irish far-right party.
Three policemen were injured.
