Paris - A French aid worker abducted in the streets of Kabul one month ago has been freed, French Foreign Minister Bernard Kouchner said Wednesday.

Dany Egreteau, 32, who worked for the NGO Solidarity Laique, was kidnapped by armed men on November 3 while walking in the centre of the Afghan capital.

An Afghan secret service agent who tried to prevent the kidnapping was shot to death by the abductors.

In a statement, Kouchner thanked French and Afghan authorities for their efforts in obtaining Egreteau's release, and slammed the kidnappers for targeting aid workers.

"The work of humanitarian organizations at the side of the Afghan people, to help Afghanistan on the way to peace and development, is indispensable. To target the NGOs and their personnel... is unacceptable," Kouchner said.
