Russia on Sunday said it had struck at weapons supplied to Ukraine by the United States and European countries and destroyed a runway at a military airfield near the Ukrainian city of Odesa, news agency Reuters reported. The defence ministry said it used high-precision Onyx missiles to strike the airfield, after Ukraine accused Russia of knocking out a newly constructed runway at the main airport of Odesa.

The defence ministry also said its air defence systems had shot down two Ukrainian Su-24m bombers over the Kharkiv region overnight.
