People display candles in a broken bus shelter, one of the targets of the attack at Place Saint-Lambert in Liege, Belgium. The lone gunman armed with grenades who went on a murderous spree in the city shot himself in the head after killing three youngsters and a woman in the crowded square, the prosecutor said Wednesday. “Nordine Amrani committed suicide with a bullet to the head,” said Daniele Reynders at a press conference. “He left no message to explain his act.”  (Philippe Huguen / AFP / Getty Images)
