Seven, 38, was arrested in the Netherlands during a routine traffic control last August. According to the Turkish authorities Seven carried out terrorist attacks for the rebel Kurdistan Workers' Party (PKK) that left 15 people dead, ANP said.

The judges ordered Seven's release from police custody but he was immediately re-arrested in court because he illegally entered the Netherlands, ANP said. According to the news agency Seven has asked for political asylum in France.

The Dutch court said that the documents that formed the basis for the extradition request were in Turkish and the English translation provided was so poor that it could not be used.

The court also rejected a request by the Dutch justice minister for more time to translate the Turkish documents as the judges said that Seven had been in detention since August 1, 2006, leaving the authorities plenty of time to come up with an acceptable translation, ANP said.

A month ago the Dutch Supreme Court also blocked the extradition to Turkey of PKK leader Nuriye Kesbir, saying that she could face torture there.

The PKK has fought for Kurdish self-rule in southeast Turkey since 1984. It called off a five-year unilateral ceasefire in June 2004.

Kesbir, as PKK leader, worked alongside Osman Ocalan, the brother of former PKK leader Abdullah Ocalan who has been serving a life sentence in Turkey since 1999.

She is accused by Turkey of taking part in at least 25 attacks in eastern Turkey between 1993 and 1995. She denies any involvement in the attacks and claims she dealt only with the women's issues as a member of the PKK's presidential council.
