A German citizen is believed to have been kidnapped in Afghanistan, the German foreign ministry has said.
The man has been missing since 28 June and Berlin says they have to assume he has been kidnapped, based "on the indications we have", a spokesman said.
He did not give the man's name but said the man did not work for the German government, was not a German aid worker or a journalist.
A number of foreign citizens have been abducted in Afghanistan since 2001.
Italian reporter Daniele Mastrogiacomo was released in March this year after five Taleban members were freed in exchange, but his driver, Sayed Agha, was beheaded.
Two French aid workers were also released in April and May this year after being kidnapped in Afghanistan.
