BBC News reports a 20-year-old man is going on trial in Germany on charges of fighting for Islamic State (IS) militants in Syria. Prosecutors say Kreshnik Berisha received weapons training and combat experience with the jihadist militants over several months last year. He was arrested at Frankfurt airport last December while on his way home. The trial - the first in Germany for alleged membership of IS - comes amid growing alarm at the potential threat posed by jihadis returning to Europe. IS is thought to have attracted hundreds of recruits from European countries in its battle to establish what it describes as a "caliphate," spanning a borderless stretch of Syria and Iraq. Jihadist groups in Syria are thought to have attracted some 400 Islamists from Germany alone. Germany announced on Friday that it would seek to prosecute anyone who tried to recruit for IS or spread the group's propaganda. The German government also recently said it would arm Iraq's Kurds in their fight against IS.
