German consumer morale fell for the first time in more than 1-1/2 years heading into September as shoppers grew more wary of the impact on Europe's largest economy of sanctions on Russia and other international conflicts.

Market research group GfK said on Wednesday its forward-looking consumer sentiment indicator, based on a survey of around 2,000 Germans, fell to 8.6 going into September from a downwardly revised 8.9 in August.
