THE HAGUE, Oct 2, 2008 (AFP) - Dutch judges jailed a radical Muslim for nine years Thursday for belonging to a terror group that planned attacks on political and civil targets in the Netherlands, news agency ANP reported.

The judgment raised by one year the prison sentence imposed on Samir Azzouz by a lower court in December 2006 for his involvement in preparing an attack on Dutch politicians and intelligence services.

In the earlier judgment, trial judges cleared Azzouz, a Dutchman of Moroccan origin, of membership of a terror group since preparations for an attack had been 'clumsy and primitive' and 'in a nascent stage'.

Prosecutors had asked for a 15-year sentence, saying Azzouz and his group had maps of intelligence service headquarters, parliament, and the Schiphol airport in Amsterdam as well as weapons and explosives.

The case was subsequently re-opened on appeal, and judges found on Thursday that Azzouz had been wrongly cleared of belonging to a terror group.

He had in fact acted as an organiser of the group and recruited volunteers for the armed struggle against 'the enemies of Islam', said ANP.

One collaborator was jailed for eight years, and three others for between three months and six years.

Prosecutors claimed the five belonged to a group with links to the Hofsted terror organisation blamed for the 2004 murder of Dutch filmmaker Theo van Gogh, an outspoken critic of Islam.
