Earlier this month, NATO states Romania and Latvia saw Russian drones crash after breaching their airspace, prompting official calls for measures to act jointly to counter Russia air incursions.

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.

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."

Dmitry Peskov, the spokesperson for Kremlin leader Vladimir Putin, has stated that NATO's refusal to take Vladimir Putin's statements seriously regarding the supposed consequences of allowing Ukraine to attack Russian territory with long-range Western weapons is "provocative and dangerous".

On Wednesday, the Kremlin condemned comments by outgoing NATO chief Jens Stoltenberg as “dangerous”, Reuters reports. Stoltenberg had suggested that allowing Ukraine to use Western long-range missiles to strike Russian territory would not trigger an escalation from Moscow.
