July 26 (UPI) — Romania said Sunday it shot down a Russian drone over its territorial waters in the Black Sea, marking the the third such incident in a week and prompting the NATO member to summon Russia’s ambassador.

Defense Minister Radu Miruța said a Romanian Air Force F-16 Fighting Falcon aircraft shot down a drone that had penetrated into Romanian airspace near the delta of the River Danube in the Black Sea.

The drone was first detected by radar outside Romanian airspace before it continued without authorization into its national territory at 10:08 a.m. above Sulina, Miruta said in a statement.

Five minutes later it was shot down over the Black Sea.

“Romania’s safety is not defended with slogans. Congratulations to the pilots and ground support teams!” he said. “Each such incident confirms that Russia’s war of aggression against Ukraine continues to generate risks beyond Ukrainian borders.”

Foreign Minister Oana Toiu added that Bucharest has summoned the Russian ambassador and will weigh whether to lodge a diplomatic protest over the trio of recent incidents.

An initial investigation has revealed that a drone shot down on Friday “is of the Shahed type, used by the Russian Federation in the war of aggression against Ukraine,” Toiu said.

“It is inadmissible and intolerable for the Russian Federation to continue violating Romania’s airspace, which is, at the same time, NATO airspace and European Union airspace.

“Such actions are unacceptable, and we treat them with the utmost seriousness, alongside our allies,” she said.

Romanian President Nicușor Dan similarly congratulated the pilots who carried out the missions and criticized Moscow for its “continued violation” of Romanian airspace.

Prior to Sunday’s latest incident, Ukrainian Foreign Minister Andrii Sybiha urged allies to craft a “comprehensive deterrence package” against Russia over its violations of Romanian airspace, calling them “a clear demonstration of the Kremlin’s complete disregard for international law, national sovereignty, and European security.

“The response must match the scale of the threat,” he said. “We need a comprehensive deterrence package for Ukraine and Europe: stronger sanctions, maximum pressure on Russia, and a joint effort to shield Europe’s skies from Russian terror.”
