The complaint, raised by three survivors of the April 2011 tragedy that caused the deaths of 63 migrants in the Mediterranean Sea, accuses the Belgian army, who were present in the area, of failing to respond to distress signals received from the migrants' boat. According to the press release of the International Federation for Human Rights (FIDH), 72 people were left to drift at sea for 15 days, despite their calls for help being registered by the NATO coordination centre and direct contact with an airplane, helicopters and military vessels.
