Romania on Friday said a Russian drone carrying explosives crashed in the eastern city of Galați, causing a fire on the roof of a residential apartment block.
"We do consider it the full responsibility of the Russian Federation that our civilians were put at risk", said Oana Toiu, Romania's foreign minister, interviewed by Euronews.
"We do have the final confirmation from the teams on the ground that the drone is a Russian drone and it was carrying explosive."
Since the drone crash, Romanian President Nicușor Dan has declared the Russian consul in Constanta persona non grata and said the Russian consulate in the Black Sea port city would be closed.
"We consider this a clear message to Russia that it is unacceptable and that the security and safety of our citizens is our prime concern", said Toiu.
Russian President Putin reacts
Meanwhile, Russian President Vladimir Putin questioned the preliminary conclusions regarding the incident, suggesting that the aircraft may have been Ukrainian rather than Russian, according to Reuters and Kyiv Post.
Speaking from Astana Putin said "Nobody can say anything about the origin of one drone or another until there is an expertise of that flying device".
The Kremlin leader said he had only recently learned about the incident and stated that Russia should have access to the drone’s remains in order to conduct its own analysis.
“Let them hand it over to us, we will conduct an objective investigation, and only then, in this case, will we give an assessment of what happened.” Putin said, quoted by the Kyiv Post.
Bucharest has claimed that the aircraft was of Russian origin, but Moscow has repeatedly denied responsibility for similar incidents in the airspace of NATO states.
Speaking on previous drone incidents that have landed in states such as Poland or the Baltic states, Putin commented "it would turn out that the incidents had absolutely nothing to do with Russian aircrafts, but rather involved drones of Ukrainian origin.”
In parallel, the Kremlin said the Russian president has been informed about the situation, and the Foreign Ministry in Moscow announced that Russia will soon react to Romania's decision to close the Russian consulate in Constanta, a measure that it considers "unjustified".
The incident in Galati has amplified diplomatic tensions between Moscow and NATO states.
European leaders condemn the incident
The incident has sparked strong criticism from leaders across Europe.
EU Commission President Ursula von der Leyen said on Friday that Russia had "crossed yet another line" and vowed to continue to put pressure on Moscow.
"We stand in full solidarity with Romania and its people," von der Leyen said, adding that the EU was prepping a 21st package of Russian sanctions.
In a statement, NATO condemned Russia’s "recklessness" and said the alliance would strengthen its defences against "all threats, including drones".
The Romanian minister welcomed this support. It "is very important because it is always important to reaffirm that the security of one is the security of all", she said.
But she also wants to look further ahead and step up the pressure on Russia.
"I have spoken with Kaja Kallas in the morning in terms of accelerating the pace for the 21st package of sanctions and we see there a clear support", declared Toiu.
