An Iraqi preacher said to be the Islamic State jihadist group's de facto leader in Germany was sentenced to 10 years and six months in prison by a German court on Wednesday. Ahmad Abdulaziz Abdullah Abdullah, better known as Abu Walaa, was accused of directing a jihadist network which radicalised young people in Europe and helped them travel to Iraq and Syria. The 37-year-old was found guilty of membership of a foreign terrorist organisation, aiding the preparation of subversive violent acts and financing terrorism. bro-kih/dlc/lc
