German prosecutors say they've arrested two men suspected of supporting the Islamic State group and searched the homes of several others.

Federal prosecutors said the two were arrested Saturday in the western city of Aachen. They were identified only as Tunisian citizen Kamel Ben Yahia S. and Russian national Yusup G. because of German privacy rules.

The Tunisian is accused of providing clothing worth over 1,100 euros ($1,400) and 3,400 euros in cash to IS, and smuggling a 17-year-old boy from Germany to Syria to join it. The Russian is accused of participating in the smuggling.

Six others suspected of helping them had their homes searched. One was temporarily detained.

Prosecutors say they searched the homes of seven more people suspected of supporting Ahrar al-Sham, an ultraconservative Syrian rebel group.
