Jihadists abducted Soumaïla Cissé in March, while Sophie Pétronin was taken in 2016
Jihadists in Mali have freed a prominent opposition leader kidnapped earlier this year and a French aid worker held captive for almost four years, in a major exchange of prisoners with the country’s new transition government.
Soumaïla Cissé, a 70-year-old former presidential candidate, was kidnapped in March while campaigning in his home town in the restive north of the country.
