Police in Germany say they have arrested two Islamic extremists during dawn raids in the central city of Goettingen.<br /><br /> The men – a 27-year-old Algerian and a 23-year-old Nigerian – who have not been named, were detained as part of an investigation into a possible terror attack. <br /><br /> Officials say the two were well known to the authorities having long been part of the Salafist scene in the city.<br /><br /> The head of Goettingen police Uwe Luehrig said: ‘‘During the raid we found weaponry which was bought without requiring a permit and had later been converted in order to fire live rounds of ammunition. We also found ammunition and flags of the Islamic State group, as well as a machete.”<br /><br /> German authorities concerns are said to have grown last weekend after intelligence revealed that the suspects might launch an attack. <br /><br /> Police have not said how concrete and advanced their plans were, or what exactly they were plotting to do.<br />
