Ukraine claims to have shot down five Russian planes and one attack helicopter in the east of the country.
According to the Ukrainian Defense Forces leadership, the planes and the helicopter were shot down in eastern Ukraine, near the areas controlled by Russian-backed separatists.
The information has not been confirmed by Moscow, which earlier on Thursday rejected a report that a Russian plane had been shot down in Ukraine.
