A picture taken on March 25, 2016 shows people gathering at a makeshift memorial in tribute to the victims of the Brussels terror attacks, on Place de la Bourse square in Brussels. Grieving Belgians held prayers in the rain in a central Brussels square carpeted with flowers and tributes to the 31 dead and 300 wounded in March 22 carnage in Brussels, but there was also growing anger at the government for letting a string of militants slip through the net. / AFP / Belga / LAURIE DIEFFEMBACQ / Belgium OUT (Photo credit should read LAURIE DIEFFEMBACQ/AFP/Getty Images)
