Russia's defence ministry said on Sunday 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.
The 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.
Odesa regional governor Maksym Marchenko said Russia had used a Bastion missile, launched from Crimea.
Reuters could not immediately verify the reports.
Russia's defence ministry also said its air defence systems had shot down two Ukrainian Su-24m bombers over the Kharkiv region overnight.
