Brussels: NATO issued a stern warning to Russia on Tuesday, stating it will use all available means to defend its members against further breaches of their airspace. This comes in the wake of Russian drones being downed over Poland on September 10 and Estonia's report of an unauthorised intrusion by three Russian fighter jets last week. On September 19, Estonia reported that three Russian MiG-31 fighter jets entered its airspace for approximately 12 minutes before being intercepted and forced to retreat. Rising Concerns Over Russian ProvocationsThe increased breaching of NATO airspace by Russian military aircraft has raised alarms across allied nations. Britain’s Foreign Secretary Yvette Cooper reaffirmed the UK’s readiness to confront unauthorised Russian flights, warning that Moscow’s reckless actions risk direct armed conflict with NATO.
