Demonstrators hold placards reading ” No to racism” on December 17, 2011 during an antiracist demonstration in Milan in memory of the two Senegalese who were killed in Florence on December 13 by a far-right Italian. Witnesses said they saw the gunman calmly getting out of a car at a street market on Piazza Dalmazia, north of the city centre, and firing three shots that instantly killed the two Senegalese vendors and seriously wounded a third.
