A Russian diplomat was found dead last month outside the country's embassy in the German capital, it has emerged.
The man's body was discovered on the pavement on 19 October by police guarding the Berlin compound, Der Spiegel website reported.
Germany's foreign ministry confirmed the diplomat's death to reporters but would not give further details.
Police in Berlin have not publicly commented on the death, which was reported for the first time on Friday.
Der Spiegel said the embassy called it a "tragic accident" on which it would not comment "for ethical reasons".
The man has not been officially named, but reports say he was 35 years old and listed as a second secretary of the Russian embassy.
Investigative website Bellingcat said it had used open source data to establish the man was the son of the deputy director of the Second Service of Russia's FSB intelligence agency.
Germany has accused Russia of ordering the murder.
Second Service officials have also been linked to the poisoning of Russian opposition figure Alexei Navalny in 2020.
According to Der Spiegel, the Russian embassy did not agree to a post-mortem examination following the diplomat's death last month, and his body has now been returned to Russia.
