The trial of seven men accused of involvement in a network recruiting young French men for armed groups fighting against US forces in Iraq has begun in Paris.
The men have been accused of "criminal conspiracy with a terrorist organisation" and face up to 10 years in jail if they are found guilty.
The suspects were arrested following an investigation launched in 2004, when Redouane El-Hakim, a young Frenchman, was found dead in the Iraqi city of Fallujah.
His brother Boubakeur El-Hakim is one of the seven men who went on trial on Wednesday.
Five of the men are French nationals, while one is Moroccan and another Algerian.
According to prosecutors, the network's ringleader was Farid Benyettou, who attended a mosque in north-east Paris and admits encouraging several of his followers to join fighters in Iraq.
At least one dozen youths, many of them friends since childhood, are believed to have travelled to fight US-led forces in Iraq, from 2004 onwards.
Three died in a suicide bombing in Iraq, while several others were injured or arrested in Iraq and neighbouring Syria.
The recruits were allegedly sent first to Syria, from where they travelled to Iraq. Two of the men on trial were taken into custody in 2005 as they prepared to fly to Syria.
The trial dealt with mostly procedural issues as it opened. It is scheduled to end March 28.
