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 approval of the $7.2 billion deal for the fifth-generation fighter comes as NATO allies are worried about Russian aggression.

NATO countries are becoming increasingly vocal about their capabilities to shoot down Russia drones and missiles, as Romania and Latvia become the latest members of the Western alliance to report Moscow violated their airspace.

Latvia and Romania say the drones violated their airspace, one flying into Romania during attacks on neighboring Ukraine, another crashing in Latvia.
