German prosecutors say they've detained two more people following weekend raids on suspected supporters of the Islamic State group and an ultraconservative Syrian rebel organization, Ahrar al-Sham.

Two suspected IS supporters were arrested in western Germany Saturday. Authorities searched the homes of 13 more people suspected of links to the two groups.

Federal prosecutors said Monday that one of those people, a German-Moroccan dual national identified only as Mounir R., has now been taken into custody over accusations he provided IS with clothing worth 1,100 euros ($1,400) and transferred 1,000 euros to an IS member in Syria. They say he planned to leave for Syria soon himself.

Lebanese national Kassem El R. also was arrested, accused of organizing the delivery of military clothing and boots to Ahrar al-Sham.
