Russia has announced the expulsion of a Romanian diplomat from its embassy in Moscow, citing retaliation for Romania declaring a Russian embassy employee *persona non grata*. The Russian Foreign Ministry, as reported by Interfax, framed the move as a response to Bucharest’s prior action. This reciprocal expulsion escalates tensions between the two countries, already strained by recent events. The initial Romanian decision was made without public justification, though it is widely believed to be linked to repeated incursions of Russian drones into Romanian airspace. This latest development follows a pattern of tit-for-tat diplomatic responses between Russia and various nations amid ongoing geopolitical conflicts. The exchange highlights the sensitivity surrounding security concerns and diplomatic protocol in the region. Further repercussions for bilateral relations are anticipated.
