Police in Greece say the home of Germany's ambassador to Athens was sprayed with gunfire from automatic weapons in an overnight attack that caused no injuries.

Anti-terrorism police cordoned off streets around the official residence of Ambassador Wolfgang Dold following the attack Monday in the Halandri area of the capital and recovered more than 60 bullet casings from the scene.

No group has claimed responsibility for attack.

Lead bailout lender Germany is often the subject of strong criticism in Greece, which is suffering through a sixth year of recession and tough austerity measures imposed as a condition of the country's international rescue loans.
