Laurent Fabius said on French radio Monday that the strikes hit the Kidal region overnight, near the border with Algeria. It's part of a broader effort to cut off supplies to radical fighters who had taken over much of the African country and enforced harsh rules on the population.
Fabius said on France-Inter radio, "They cannot stay there a long time unless they have new supplies."
The French intervened in Mali on Jan. 11 to stem the advance of the al-Qaida-linked fighters.
Fabius also said that France wants African forces to assume security responsibility for the historic city of Timbuktu "very fast," perhaps as soon as Tuesday.
