Girls wearing veils demonstrate to show their solidarity, on January 10, 2015 at Piazza Duomo in Milan, after three days of bloody attacks in which 17 people died at the hands of Islamic extremists in France. The three-day killing spree by three Islamic militants ended on Friday following a massive police operation triggered by Wednesday’s attack on the satirical weekly Charlie Hebdo in which 12 people were murdered. All three gunmen died in final confrontations with police. AFP PHOTO / GIUSEPPE ARESU
