Romania said on Saturday that it had shot down a second drone breaching national airspace in as many days over a sparsely populated area near the border with Ukraine.

Axar.az reports, citing Reuters, the first drone, which Romanian prosecutors investigating the fragments said was Russian, was shot down by the NATO state on Friday, the first time it has done so after dozens of airspace breaches.

President Nicusor Dan took to social media to say the second drone had been shot down at 8:30 a.m. (0530 GMT), 10 km (6 miles) west of Sfantu Gheorghe in the Danube Delta.

The defense ministry said the airspace breach had been spotted by radar at 8:22 a.m., and two F-16 fighter jets had been scrambled.

It did not specify the origin of Saturday’s drone; prosecutors said the drone downed on Friday had been Russian.
