In a tit-for-tat move, Romania declared a top Russian diplomat in Bucharest persona non grata on Tuesday and ordered him to leave the country in 48 hours.
On Monday, Russia's Federal Security Service (FSB) announced that Gabriel Grecu, first secretary of the political department of the Romanian Embassy in Moscow, had been detained in Moscow while trying to obtain military secrets from a Russian national.
Grecu was quickly declared persona non grata and ordered to leave the country within 48 hours.
Romania's Foreign Ministry said the Russian diplomat had "equivalent ranking" to Grecu - i.e., first secretary, but did not release any names.
There has been no comment from Moscow yet.
