NATO must take "robust coordinated" measures in response to incidents where Russian missiles or drones launched by Ukraine invade the alliance's airspace, according to Romanian Defense Minister Angel Tîlvăr.

Romanian Defence Minister Angel Tîlvăr says the countries of the Bucharest Nine (B9) "are deeply concerned" by numerous instances of Russian drones and missiles entering the Alliance's airspace and a "decisive" response from NATO is required.

Speaking at a meeting of the Bucharest Nine (B9) format, Romanian Defense Minister Angel Tilvar called for "enforcing the rotational air defense and integrated anti-missile model as soon as possible."

KYIV, Ukraine (AP) — A Russian drone violated Romania's airspace during nighttime attacks on neighboring Ukraine, the NATO member reported Sunday, urging Moscow to stop what it described as an escalation.

NATO must enact a "robust coordinated" response to incidents in which Russian missiles or drones fired at Ukraine enter the alliance's airspace, Romanian Defence Minister Angel Tilvar said on Wednesday.

The defense ministers of Romania, Poland, and Latvia have signed a joint letter to NATO allies, urging the immediate implementation of NATO’s air defense rotation model. The letter also calls for the strengthening of NATO’s deterrence, surveillance, reconnaissance, and air patrol efforts along the alliance’s eastern flank.

Latvia’s president said NATO needs to have the ability to shoot down Russian drones that stray into member states’ territory as he called for increased air defenses on the alliance’s eastern flank.

Defense ministers from from nine eastern European nations urged NATO to prepare a “collective answer” to mounting cases of airspace violations by Russia among nations bordering Ukraine.
