Romanian authorities shot down a drone over the country's airspace on Sunday morning, marking the third such incident in recent days.
The Ministry of Foreign Affairs summoned the Russian ambassador to Bucharest for an urgent meeting to protest the violation.
Foreign Minister Oana Ţoiu described the continued incursions by the Russian Federation as inadmissible and intolerable, signaling a sharp deterioration in bilateral relations.
The drone was intercepted at 10:13 local time by an F-16 fighter jet from the Romanian Air Force.
This latest event follows two previous airspace violations, intensifying security concerns along NATO's eastern flank.
The government's swift diplomatic response underscores the severity with which Bucharest views these breaches of sovereign territory.
