The International Committee of the Red Cross says one of its workers, a French-Tunisian woman, has been released after nearly a year in captivity in Yemen

The Red Cross said in a posting on its official Twitter account late Monday that Nourane Houas was en route to Oman after being freed. Houas was kidnapped on her way to work in Yemen's capital Sanaa on Dec. 1 by unidentified assailants.

She appeared in a video in May asking President Francois Hollande to save her life.

No group has claimed responsibility for the abduction. The abduction of foreigners is common in Yemen, where militant groups such as al-Qaida and tribesmen use hostages to raise funds through ransom payments or bargain for the release of prisoners.
