BERLIN - German authorities are investigating whether hundreds of unsolved killings and attempted killings over the past two decades were committed by neo-Nazis.
The 746 cases with no known suspects involved 849 victims and took place between 1990 and 2011. The period spans the time between German reunification and the discovery of a neo-Nazi cell suspected of committing 10 murders.
That prompted a fundamental review of how German security services deal with far-right crimes.
Interior Ministry spokesman Hendrik Loerges confirmed the probe first reported Wednesday by Germany's Neue Osnabruecker Zeitung newspaper.
Independent researchers and anti-racism campaigners have long criticized the criteria used by German authorities to classify a crime as being motivated by far-right ideology.
Currently some 63 cases during the 21-year period are classified as far-right crimes.
