During his visit to Tehran, German Foreign Minister Frank-Walter Steinmeier confirmed on Saturday that the German aid worker kidnapped in Afghanistan had been released.

She was "doing well considering the circumstances," Germany's top diplomat said.

The details of her rescue have not been made public.

The aid worker, who has not been named, was abducted in mid-August in Kabul, in the district of Kala-e-Fatullah, where many foreigners live. Two armed men stopped her car and pulled her out by force.

According to news agency DPA, she was working for Germany's aid agency GIZ. GIZ operates in more than 130 countries worldwide.

"We are very relieved and happy that our employee is free again," GIZ spokesperson Tanja Gönner told DPA news agency on Saturday.

In spring, another GIZ aid worker was abducted by the Taliban in northern Afghanistan. After six months, he managed to escape. In October 2014, a hostage who had been a member of the German aid organization Welthungerhilfe was released after more than two-and-a-half years in captivity.
