The ten were part of a group of 15 Kurds seized earlier this week in an investigation headed by France's top anti-terrorist judge, Jean-Louis Bruguiere.

The other five had earlier had investigations opened against them on suspicion of "criminal association in relation with a terrorist enterprise" as well as "funding terrorism" and "organized money-laundering".

Fourteen of the group, most of whom are from Turkey, have been remanded into custody.

The PKK is regarded as a terrorist organization by the European Union, the United States and Turkey.

Ten other Kurds were to go before a judge Friday.
