Anti-gay marriage protesters, calling themselves "Les Veilleurs" (The Watchmen), take part in a vigil on August 28, 2013 in Nantes, western France. They began their walk 25 days ago to show their opposition to same-sex marriages and they should arrive on August 31 in Paris. France on May 18 became the 14th country to legalize same-sex marriage after President Francois Hollande signed the measure into law following months of bitter debate and demonstrations.
