Romania 's Foreign Ministry has announced that Moscow had been told that a Russian diplomat would be expelled from Bucharest in retaliation to the expulsion of a Romanian diplomat from Moscow a day earlier.
The Ministry said in a statement on Tuesday that it would "declare a diplomat in the [Russian] Embassy - with an equivalent ranking - as persona non grata" in retaliation to the Russian move, RTTNews informs.
Russia 's FSB security agency said on Monday it had detained a Romanian diplomat for spying, and ordered him to leave the country within 48 hours.
The FSB named him as Gabriel Grecu, who was accredited as the first secretary at the Romanian embassy in Moscow, and said he had been caught trying to receive secret military information and had "spying equipment" on him, AFP reports.
