Youths wave French flags in clashes with riot police during incidents at the end of a protest march called, "La Manif pour Tous" (Demonstration for All) against France's legalisation of same-sex marriage, in Paris, May 26, 2013. The French parliament on April 23 approved a law allowing same-sex couples to marry and to adopt children, a flagship reform pledge by the French president, which has often sparked violent street protests, and a rise in homophobic attacks.[Photo/Agencies]
