The Tunisian armed forces found the body of Khalifa al-Sultani, a 21-year-old shepherd, in Jebel Mghila in the central governorate of Sidi Bouzid on June 3, after combing the exact area where the body of his brother, Mabrouk, was previously found in November 2015.
On the same day, the Islamic State (IS) claimed responsibility for Khalifa's death. Back in 2015, IS posted a video showing the final moments of Mabrouk, 16, before he was beheaded, accusing him of cooperating with the Tunisian military services.
