Mourners remember Liege victims

Prime Minister Elio Di Rupo and Crown Prince Philippe stood with the Liege mayor in a solemn ceremony on the same city centre cobblestones that were stained with blood in the attack a week ago.
Investigators are looking for clues as to why Nordine Amrani, a 33-year-old with a criminal record, swept into the central square in the middle of the Christmas shopping season to unleash the rampage that killed four people and wounded 123 others. He took his own life immediately afterwards.
