MANILA/MARAWI CITY, Philippines, June 23 (Reuters) – Before they formed one of the most dreaded militant groups in the Philippines and pledged loyalty to Islamic State, the Mautes were a wealthy, political family in the southern region of Mindanao, largely influenced by the matriarch, Farhana.
Soft-spoken and reserved, 60-year-old Farhana Maute owns property in Mindanao and in Manila, and runs a construction business, say people who know the family and security analysts who have scrutinised its background.
