Hassan Mekki, a 32-year-old Sudanese migrant, shows scars on his back in Athens December 5, 2012. Mekki, who fled conflict in his country in hopes of a better life in Europe, said he was attacked by a group of men holding Greek flags and left with the deep wounds on his back, throat and neck in August 2012, about five months after he illegally entered Greece. Mekki was walking in Athens with a friend from Mauritania when black-shirted men on motorcycles holding Greek flags and shouting "Go home black" and other racists insults came up and knocked him out with a blow to the head. He was covered in blood when he regained consciousness and only later realized that his attackers, which he says were likely tied to the far-right Golden Dawn party, had left large gashes resembling an "X" across his back. "I don't have the right papers, so I can't go anywhere to ask for help," Mekki said. "I can't sleep. I'm scared, maybe they will follow me and my life is in danger now."
