France’s political division was on full display at rival May Day rallies held across the country, less than a week until the final run-off between French presidential candidates Emmanuel Macron and Marine Le Pen.In Paris, a rally organised by the hard-left CGT trade union marched to Place de la Nation, with occasional clashes reported on the fringes between youths and riot police. Police shot tear gas and used water cannons as they came under attack by Molotov cocktails. A number of officers reported injuries, with one suffering third-degree burns.
