Russia said on Friday (Mar 17) that all fighter jets supplied to Ukraine by Western nations would be destroyed after NATO members Poland and Slovakia pledged to send MiG-29 jets to Kyiv.

Since Russia’s invasion last year NATO countries have sent billions of dollars of military aid to Ukraine, as Kyiv asks for weapons it says are vital to fend off Russian advances.

Moscow has accused the West of directly participating in the conflict through supplying weapons to Ukraine, and has warned before that NATO weapons were legitimate targets for its forces.
