Federal prosecutors in Germany said on Tuesday that they have indicted eight people for supporting foreign terrorism and being members of a criminal organisations.

The eight - seven men and one woman aged between 17 and 30 - are accused of supporting al-Qaeda, al-Qaeda in Iraq and the Kurdish group Ansar al-Islam, through their membership of the German chapter of the so-called Global Islamic Media Front (GIMF).

All but the 17-year-old, who is Turkish, are German citizens.

An arrest warrant has been issued for the suspects, all of whom remain at large in Germany, a spokesman for the Federal Prosecutor's Office said.

A statement released by the office said that the GIMF was a 'militant Islamist organisation that had the goal of supporting the global jihad through the internet.'
