The Ministry of Foreign Affairs summoned the Ambassador of the Russian Federation to Sofia Eleonora Mitrofanova in connection with the deliberate violation of the airspace of Poland, our NATO ally and EU partner, by the entry of Russian military unmanned aerial vehicles on September 10, 2025. This was announced by the press center of the Ministry of Foreign Affairs.

The Director General for Political Affairs of the Ministry of Foreign Affairs, Gergana Karadjova, delivered a written demarche to Ambassador Mitrofanova, through which the Republic of Bulgaria condemns in the most categorical manner possible the deliberate violation of Poland's airspace and expresses absolute solidarity with its ally and partner.

Bulgaria views these irresponsible actions of the Russian side, including the entry of a Russian drone into Romanian airspace on September 13, 2025, as a threat to the security of European citizens, regional stability and international peace.

This provocation by the Russian side is not an isolated incident, but is part of a series of unacceptable violations of the airspace of a number of EU and NATO member states since 2022, pointing more to an escalating campaign by Russia than a will to de-escalate.

The gross violation of Euro-Atlantic airspace and the ongoing massive Russian strikes against civilians and civilian infrastructure in Ukraine strengthen Bulgaria's determination to actively support and participate in the joint actions of our allies and partners to ensure the defense and security of NATO and the EU on the Eastern Flank, as well as diplomatic efforts to de-escalate and find a comprehensive, just and sustainable peaceful solution to the unprovoked Russian military aggression against Ukraine.

Bulgaria calls on the Russian side to immediately stop its attacks on Ukraine and dangerous provocations against European countries and to seriously engage in meaningful negotiations to end hostilities as a first step towards establishing a lasting and just peace.

B.R. Demarche is a diplomatic statement by the government or diplomatic bodies of one country to the government of another country. The demarche may contain a request, protest, warning, objection, etc., which is expressed in writing or orally. It is more than a note - a note is a type of remark, while a demarche is an official protest action.
