French police said they arrested 45 people in Paris and that 12 officers had been injured during traditional May Day protests on Wednesday, though the demonstrations were far more subdued than last year.

Riot police used tear gas and batons to disperse some of the demonstrators. Police put the number of protesters in the French capital at about 18,000, though the hard-left CGT union put the figure at around 50,000.

Protesters were mainly angry about the cost of living and reform of unemployment benefits, though some also waved Palestinians flags to show solidarity with the people of Gaza.
