Greek Ambassador to Moscow Andreas Fryganas was summoned by the Russian Foreign Ministry to protest the expulsion of two Russian diplomats and the denial of entry to two more Russian citizens, Tass news agency reported on Friday.

Tass quoted the Russian Foreign Ministry as saying, "On July 13, the Russian Foreign Ministry summoned Head of the Greek Mission in Moscow Fryganas Andreas, to whom [the ministry] expressed a strong protest in relation to the expulsion of two Russian diplomats and the ban of two Russian citizens from entering the country. We stressed that we find these actions absolutely unfounded, not supported by the facts from the Greek side, coming in conflict with the nature of our bilateral relations and capable of causing them serious damage."

The Russian ministry also accused Washington as being "behind the Greek government’s anti-Russian decision, timed to the opening of the NATO summit," Tass said.
