Tensions between Athens and Moscow have been running high recently, as in July, Greece expelled two Russian diplomats from the country over national security concerns, prompting Russia to retaliate.

Axar.az informs citing Sputnik.

Greece has recalled its ambassador to Russia, Andreas Friganas, the source told.

"The decision has been made. The decision was made personally by Greek Minister of Foreign Affairs Nikos Kotzias," the source said.

On Monday, the Greek envoy was summoned to the Russian Foreign Ministry, where he received a note where Moscow rejected all accusations and announced that the retaliation would follow.

Earlier this summer, Athens expelled two Russian diplomats and imposed a travel ban on two more, accusing them of meddling in security issues and attempting to bribe Greek officials.

Explaining the decision over the Russian diplomats, Athens stated they intended to thwart a deal between the Former Yugoslav Republic of Macedonia (FYROM) and Greece, which would allow Macedonia to join NATO.

A decades-long conflict between Greece and Macedonia was settled this June, after Skopje decided to change the name of the country.
