"Fourteen Ukrainian UAVs were suppressed by electronic warfare, of which 11 drones crashed in the Black Sea, and three more fell on the territory of the peninsula," the statement said.
It added that three more drones were destroyed by air defense systems.
Sergey Aksyonov, the Russian-installed head of Crimea, said the drones hit an ammunition depot in the Dzhankoi district.
He claimed drone debris also damaged a private house in the Kirovske district, adding that population of nearby villages in the Dzhankoi district were being evacuated.
He also said that railway traffic in the district and the Dzhankoi-Simferopol highway was temporarily suspended.
Ukrainian officials have not yet commented on Russia's claims, which could not be independently verified.
