(Christian Charisius/dpa via AP)BERLIN -- A Hamburg court on Wednesday convicted and sentenced seven members and one supporter of the right-wing extremist group “Last Defense Wave” to prison on charges including attempted murder, arson and aggravated assault. The Hanseatic Higher Regional Court also convicted the defendants of being members or supporters of a terrorist organization. The young men, who were between 14 and 21 years old at the time, were tried under Germany’s juvenile criminal law and given sentences between one and a half to five years in prison. The sentence for the youngest defendant — one and a half years in prison — was suspended, German news agency dpa reported. In June, two more teenagers were detained in Thuringia for alleged membership in the “Last Defense Wave" group, dpa reported.
