Romania expelled a Russian diplomat on May 29 [1] after a Russian drone entered Romanian airspace and struck a border town.

The incident marks a significant escalation in tensions on NATO's eastern flank, as the incursion is viewed as a direct breach of Romanian sovereignty and a test of the alliance's resolve.

The strike occurred in a border town near Galaţi, located on the eastern frontier with Ukraine [1]. President Nicușor Dan led international outrage following the attack, which prompted the immediate diplomatic expulsion of a Russian official [1].

Ukrainian President Volodymyr Zelenskyy expressed solidarity with the Romanian government. "Ukraine is ready to support Romania," Zelenskyy said [1].

Czech President Petr Pavel called for a more aggressive response from the North Atlantic Treaty Organization to deter further incursions. Pavel said Nato must show its teeth and consider options such as cutting off Russian banks from the global financial system or shooting down violating jets [1].

The diplomatic fallout comes as Russia continues to operate drones near the borders of NATO member states. The Romanian government has not released further details regarding the specific diplomat expelled, or the extent of the damage in the town near Galaţi [1].

"Ukraine is ready to support Romania."

This incident underscores the increasing volatility of the border zones between NATO members and the conflict in Ukraine. By expelling a diplomat and calling for harsher financial or military countermeasures, Romania and its allies are signaling that airspace violations will no longer be treated as accidental errors, but as provocative acts requiring a coordinated collective response.
