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.

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.

The defence ministers of Romania, Poland and Latvia have written a joint letter to their NATO allies stressing the need to immediately strengthen air defence efforts on the Alliance's eastern flank. Source: Delfi,
