Gunshots were fired at the residence of Wolfgang Dold, the German ambassador to Greece, in Athens on Monday.
At least four shots hit the metal gate outside the home, authorities said.
No one was injured.
The attackers are so far unidentified.
“Anti-German sentiment has grown during Greece’s prolonged economic crisis, and many of those struggling with record unemployment and plummeting living standards blame Germany’s insistence on fiscal rigor for their economic woes,” according to Reuters.
“Germany is the biggest single contributing nation to Greece’s 240-billion euro bailouts which have kept the country afloat since 2010 and saved it from bankruptcy.”
The attack was a “cowardly terrorist act clearly targeting Greece’s image abroad a few days before the start of the Greek presidency,” Greek Foreign Minister Evangelos Venizelos said in a statement.
