In a statement released on Wednesday, the Russian Foreign Ministry said the “politicized approach to the investigation is inappropriate” and promised to take “reciprocal measures.”
Separately, Kremlin spokesman Dmitry Peskov said on the same day that there were “no serious suspicions there, and there can’t be.”
“What do Russian authorities have to do with it?” he asked, calling the allegation “absolutely groundless.”
Earlier in the day, the German government expelled the duo after state prosecutors announced they had “sufficient evidence” that Moscow or the Chechen government sanctioned the assassination of a Chechen separatist in Berlin, Presstv reported.
The German Foreign Office informed the Russian ambassador to Berlin, Sergei Netschajew, that two of his employees were considered personae non gratae with immediate effect, citing the Kremlin’s refusal to cooperate in investigations into the murder of Zelimkhan Khangoshvili.
Khangoshvili, 40, was shot dead in a park in the German capital just before midday on August 23. The victim was a Georgian citizen of Chechen ethnicity who fought against Russian troops in Chechnya.
Khangoshvili fled to Germany after surviving an assassination attempt in the Georgian capital, Tbilisi, in 2015. He had applied for asylum in Germany but was denied.
The German federal prosecutor said the Russian intelligence had classified Khangoshvili, an ethnic Chechen from Georgia’s Pankisi Gorge, as a member of the “terrorist” organization Caucasian Emirates.
German prosecutors said evidence suggests Russia or Chechnya may have ordered the murder of a Georgian man in Berlin.
Russia has vehemently rejected the allegation from Germany that Moscow may have been behind the murder.
