The German Foreign Ministry has said the German woman kidnapped in Afghanistan has been freed.
The woman was abducted in the Afghan capital at gun point and had appeared in a video asking Berlin to use every effort to gain her freedom.
The video was aired by private television station Tolo and showed the woman displaying an identity card with the her name displayed on it.
A man with his face covered appeared on the video saying the abductors were not Taliban but they belonged to a special network.
He demanded the release of the group's men held by President Hamid Karzai's government.
He said details would be passed to the government through special channels.
The German Foreign Ministry declined to comment on the video, said it was in the process of analysing it.
Afghan authorities are continuing to search for the aid worker who was taken hostage from a restaurant yesterday in Kabul while she ate with her husband.
Security forces are concentrating the search for the kidnapped woman in an area of the capital close to where she was abducted at gunpoint.
The abduction is the latest in a string of Iraq-style kidnappings blamed mostly on the Taliban rather than insurgents.
Nineteen South Korean hostages are still being held by the Taliban after they were kidnapped in southern afghanistan a month ago.
A spokesman for the hardline militia said that more than a week of direct talks had failed and Taliban leaders were to decide the hostages' fate.
