Holding the pictures of the kidnapped Italian woman, and the banners of "Release Clementina" and "Kidnapping will be an eternal shame of Afghanistan", more than 400 Afghan women sat in front of a sanatorium of Afghan capital Kabul, and asked the kidnappers to set the woman free.

"The kidnapping of the lady is very bad, and great damaged theimage of Afghanistan. We hope the kidnappers can set her free as soon as possible," an old lady named Gul Ghotai told Xinhua as crying.

"Clementina is a very nice lady who often sent us food and other necessaries, and gave us hope and future," another young lady said.

The Italian woman Clementina Cantoni, working in CARE International, was kidnapped by four armed men in the center of Afghan capital Kabul at about 9 pm on Monday.

This kidnapping follows a series of warning to the about 3,000 foreigners in Kabul, that they might be the targets of attacking or arresting.
