Syrian man arrested in Germany for alleged Islamist attack plot.

German authorities have arrested a 28-year-old Syrian man in Hamburg on suspicion of planning an explosives attack motivated by Islamic extremism. The man was encouraged and supported by his 24-year-old brother. The brothers were described as being motivated by "radical Islamist and jihadist" views. Police searched properties in Hamburg and Kempten, seizing large amounts of evidence including chemical substances. In a separate case, authorities in western Germany are investigating a possible extremist motive in an attack at a gym in Duisburg last week.
