An Afghan official says a German woman has been kidnapped in Kabul.

Gul Agha Rouhani, Kabul's deputy police chief, says the woman was taken by two gunmen who stopped her car early Monday morning.

The woman, who has not been identified, is believed to be employed by German government aid agency GIZ.

No comment was immediately available from the German embassy or GIZ in Kabul. The German Foreign Office and GIZ in Berlin also did not comment.

Security in Kabul has deteriorated in recent months as Taliban insurgents have intensified their war against the Kabul government.

A German aid worker was rescued in May after being held by his kidnappers for six weeks.
