Ten people have been detained in Germany on suspicion of planning an Islamist attack using a car and guns with the goal of killing as many people as possible, prosecutors said on Friday. The suspects, ranging in age from 20 to 42, were detained in raids conducted by police in the region around Frankfurt earlier on Friday. Some of them were German. The main suspects were a 21-year old man from Offenbach, a city near Frankfurt, and two 31-year brothers from Wiesbaden, prosecutors said in statement. "They are believed to have agreed to carry out an Islamist, terrorist attack using a vehicle and guns that would kill as many 'non-believers' as possible," the statement said. "To prepare the attack, they had already made contact with different arms dealers, rented a large vehicle and collected financial assets to use for the purchase of guns and the execution of the planned murders," they added. German broadcaster Deutsche Welle said that police found more than $22,500 in cash, knives and a small amount of drugs during the raids. They are expected to appear in court on Friday to face charges including funding terrorism.
