Paris Soir - Ukraine denies targeting Bulgaria as drone explodes near pipeline

Bulgaria's defence ministry said the drone was of a type "widely used by the Ukrainian military", and the foreign minister summoned the Ukrainian ambassador for a meeting on Monday in response, her office told AFP.

Kyiv said it was "in close contact with the Bulgarian side to clarify the circumstances" of the incident, the latest case of a drone straying into NATO airspace as Ukraine fights off Russia's invasion.

"We can say with certainty that the Ukrainian Armed Forces did not intentionally direct any assets toward Bulgaria," Ukraine's foreign ministry spokesman Georgiy Tykhyi said, blaming Russia's invasion for the incident.

While the explosion caused no casualties, Bulgarian Prime Minister Rumen Radev said the amount of explosives it was carrying was "significant".

"The drone exploded in the immediate vicinity of the Kardam border-crossing with Romania," near the Black Sea in the country's northeast, "1,000 metres from the Trans-Balkan gas pipeline's compressor station," he said in a video released by the government.

After analysing the debris from the crash, Bulgaria's defence ministry however said that "currently, nothing suggests that this was a deliberate incident".

The drone eventually crashed into a sunflower field, Radev said.

The sound of the drone was recorded by border police in Romania, and then "a loud explosion accompanied by black smoke" was spotted by a Bulgarian border police patrol, Radev added, speaking after an extraordinary meeting of his cabinet's security council.

"One thing is certain: the drone was carrying a significant amount of explosives, given that it could be heard from a distance and produced such black smoke," he said.

The drone had not been detected by either of the two neighbouring countries, he added.

"As you know, identifying and neutralising these drones poses a major challenge," he added.

- Boosted surveillance -

Incidents involving drones have become increasingly frequent in recent months across eastern European countries that are NATO members and supporters of Ukraine in its conflict with Russia.

Romania has faced frequent drone incursions since the start of Russia's full-scale invasion of Ukraine in 2022 -- -- including some crashes on its territory. It ordered the expulsion of a Russian embassy staff member in late July.

Radev said that, following the latest incident, Bulgaria has boosted its surveillance and would redeploy troops and soldiers to the borders to detect drones and employ anti-drone measures.

Bulgaria, Romania and Turkey all front onto the Black Sea, an arena of drone combat by both Ukraine and Russia.

Turkish officials on Tuesday said a drone attack the previous day on two civilian vessels in the Black Sea had injured crew members. Turkey's foreign ministry said it was "deeply concerned about the escalating conflict" in the body of water.

Bulgaria in June halted its military aid to Ukraine. Radev said the country did not belong in the coalition of Kyiv's allies supplying arms and that he preferred to see diplomatic efforts to end the war.
