A Romanian F-16 fighter jet has shot down a drone that entered the country’s airspace, President Nicusor Dan has said. The drone incursion has not yet been blamed on any foreign military.

In a post on X, Dan said that the drone was intercepted around 11 am on Friday, and that an investigation has been launched. The Romanian Defense Ministry said that the drone was picked up by radar over the Black Sea earlier on Friday morning, and was tracked as it moved westward towards the port of Sulina.

It was intercepted over an “unpopulated area” around Padina, 90 km northeast of Bucharest, and destroyed with an air-to-air missile, the ministry added.

The incident is the third of its kind in Romania over the last two months. On June 5, a Ukrainian naval drone exploded near an oil terminal in Constanta, Romania’s largest Black Sea port, while three more detonated offshore. The drones were operated by the Ukrainian navy, which claimed that it lost control of the devices.

On May 29, a UAV carrying explosives crashed into an apartment building in Galati, 20km from the Ukrainian border. Authorities in Bucharest identified the drone as a Russian ‘Geran-2’ kamikaze drone, claiming that it could have been hit by Ukrainian air defenses and veered off course.

Dan’s response was dramatically different in the two cases. The Romanian president made no formal complaint when the Ukrainian naval drone entered the country’s main port while others exploded off Constanta, describing the incident as an unfortunate consequence of the “military operation led by Ukraine against Russian aggression.”

After the drone crash in Galati, Dan ordered the closure of the Russian consulate in Constanta and attempted to trigger NATO’s Article 4, which is invoked when a member state determines that their “territorial integrity…or security” is threatened. Dan also announced that he would “accelerate Romania-Ukraine cooperation on the co-production of drones” and increase military aid to Kiev.

Russia argued that its Geran drones carry higher payloads of explosives than the UAV that struck the apartment building, and that a stricken Geran would not have been able to cover the distance from Ukrainian air defense positions to Galati. Moscow suggested that the incident was used by Bucharest to justify plans made in advance – such as closing the consulate and stepping up aid to Kiev.
