Frenchwoman Isabelle Prime, who was kidnapped in war-ravaged Yemen on February 24, has been freed and will return home "in the coming hours", the French presidency said late Thursday.

"Our compatriot Isabelle Prime has been freed tonight," the statement read.

The 30-year-old, who worked as a consultant on a World Bank-funded project, was seized with her translator as they were driving to work in the capital Sanaa. Her translator was freed in March.
