Terror plot suspected in Europe

German authorities are investigating two men of Tunisian origin suspected of planning to use model airplanes for terrorist attacks, prosecutors said Tuesday. At the same time police in Germany and Belgium raided a series of sites searching for evidence of "possible attack plans and preparations." No one was arrested in Tuesday's raids, which were carried out by about 90 police in the Stuttgart and Munich areas of southern Germany and in Saxony in eastern Germany, federal prosecutors said in a statement.
