The International Committe of the Red Cross says three aid workers have been released after being held by armed insurgents for two days in Yemen's restive south.
The Geneva-based body says a foreign ICRC delegate, her Yemeni driver and a staff member of the Yemeni Red Crescent returned to Aden on Thursday.
In a statement Eric Marclay, the head of its delegation in Yemen, thanked those involved in securing the aid workers' release.
Yemeni officials said the three had been kidnapped Tuesday by the Southern Movement, a secessionist group that wants independence for the south.
Tribes in Yemen have historically used kidnapping as a way of getting concessions from the government and hostages were ordinarily well treated before being released.
