The fighter had stated should he be killed in combat he desired for his daughter to remain in Syria under the guardianship of Diaby and not be returned to his divorced wife in Belgium. HTS claimed that Diaby was extorting the mother of the fighter's daughter, his divorced wife by keeping the daughter from returning to Europe, HTS also claimed Diaby had kidnapped her and presented the case to an HTS-affiliated Sharia court.
