Denmark said on Tuesday it would expel 15 Russian diplomats, in line with steps taken by other European Union countries, after reports of mass graves being found and of civilian killings in the Ukrainian town of Bucha.
"This is another example of brutality, cruelty and war crimes, which apparently have taken place in Bucha," Danish Foreign Minister Jeppe Kofod told a press briefing.
The move comes after several other European Union countries including France and Germany on Monday said they would expel Russian diplomats.
Moscow, which claims images of executed civilians in Bucha were fake products of Ukrainian and Western propaganda aimed at discrediting Russia, said it would retaliate for the expulsion, RIA Novosti reported.
The Danish foreign ministry said that it did not want to cut diplomatic ties to Moscow and that the Russian ambassador and the rest of the embassy were not part of the expulsion.
The Danish Security and Intelligence Service said in a report earlier this year that the Russian embassy employed several intelligence officers involved in espionage.
"We want to send a clear signal to Russia that espionage on Danish soil is unacceptable," Kofod said.
