A Syrian man accused of financing the return to Europe of Islamic State (IS) group members has been arrested in Madrid, Spanish police say.
The man, who has not been named, is suspected of being part of the group’s financial structure and of sending money to fighters in Syria.
The money raised in Europe reached the jihadists through an informal transfer system known as hawala, police said.
Almost 6,000 fighters from Western Europe joined IS in Syria and Iraq.
