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.

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.
