Isabelle Prime has finally been freed after being taken hostage in Yemen earlier in February, said the French presidency.
According to the BBC, Prime is now scheduled to imminently return to France.
No details of her release have reportedly been provided.
The 30-year-old woman was working as a consultant on a World Bank-funded project when she was abducted on February 24.
Her translator Sherine Makkaoui, who was kidnapped at the same time, was released in March.
In recent years, tribesmen in Yemen have kidnapped foreigners as a means of putting pressure on the government to provide them with better services or to release their imprisoned relatives.
