Jean Gourdel (C), the father of mountain-guide Herve Gourdel, is helped by relatives during a gathering in tribute to his son who was beheaded by Jihadists linked to the Islamic State group in Algeria, on September 27, 2014 in Nice, southeastern France. Jund al-Khilifa, or "Soldiers of the Caliphate," beheaded the 55-year-old Frenchman after he was abducted on September 21 while hiking in a national park that was once a magnet for tourists but later became a sanctuary for Islamists.
