Some 900 police officers conducted raids in Vienna, Graz, and Linz after a two-year investigation into jihadist recruitment networks, arresting 13 people, including Abu Tejma, a Bosnian Serb preacher based in Vienna. The suspects are also thought to be involved in fundraising for the Islamic State. Austria’s interior ministry has said that about 150 people have sought to leave the country to fight for extremist groups in Syria and Iraq.
