A Franco-Tunisian Red Cross woman staffer kidnapped in Yemen almost a year ago was freed on Monday and taken to Muscat, the Omani foreign ministry said.

The International Committee of the Red Cross (ICRC) in Yemen confirmed in a tweet that their colleague had been freed.

Nourane Houas, a staffer with the ICRC's humanitarian protection programme in Yemen, was abducted in the Huthi rebel-held capital Sanaa in December 2015.

The Omani foreign ministry said her release was secured "at the request of the French authorities, the instructions of Sultan Qaboos and in coordination with Yemeni parties" which it did not identify.
