French hostage Isabelle Prime has been freed after six months in captivity in Yemen.

The 31-year-old had been working in Yemen for the World Bank for about a year when she was kidnapped in February.

She is now in the hands of French authorities and will be returned to France "in the coming hours," the presidential Elysee palace said.

Details of her release, including which group had been holding her, were not divulged.

Earlier this year, a video surfaced showing Ms Prime pleading for help. In the video, she appeared frail and anguished, and she urged the leaders of France and Yemen to allow her to return to France.

Chaos is rampant in impoverished Yemen, with pro-government forces fighting Shiite rebels.
