The wife of an elderly Australian doctor kidnapped by jihadists in Burkina Faso in 2016 has appealed for him to be freed in a video released on Friday. Kenneth Elliot and his wife Jocelyn were seized in the north of the West African country in January 2016, but she was released a month later. Wearing a blue veil and speaking in French, Jocelyn Elliot, 88, a humanitarian worker, appealed to the group to release her 86-year-old husband "when you see fit". Natives of the western Australian city of Perth, the couple had lived in Burkina Faso since 1972, providing humanitarian care in the country as well as neighbouring Mali and Niger. They were kidnapped in the town of Djibo near the border with Mali by the Ansar Dine group, led by Tuareg Malian rebel leader Iyad Ag Ghaly who went on to found the Al-Qaeda-linked Group to Support Islam and Muslims (GSIM). Jocelyn Elliot returned to Australia after her release. Numerous other foreign workers have been kidnapped in Burkina Faso, which has faced increasingly frequent and deadly jihadist attacks since 2015. Six hostages -- including Kenneth Elliot -- are believed to be held in a Mali camp near the Burkina border. ab/pgf/dl/har
