BERLIN: Prosecutors in Germany say they have charged six German nationals and one Pakistani with supporting Daesh or the self-styled Islamic State (IS) group and two other extremist organisations that are active in Syria.

Federal prosecutors said Friday that the seven, aged 23 to 59 and including one woman, formed a network to help facilitate and finance people's travel to Syria to join the groups, which also included Ahrar al-Sham and Jund al-Sham.

They face charges of supporting a terrorist organisation between the beginning of 2013 and September 2014.

Two of the accused are in custody, including one who is also accused of trying to recruit a man as an IS member or supporter.

German authorities say that a total of around 700 people have travelled from Germany to join extremists in Syria and Iraq.
