Five drones were shot down and four were jammed and did not hit their targets in Dzhankoi in Crimea, a Russian-installed official in the peninsula that Moscow annexed from Ukraine in 2014 said on Sunday.
There were no casualties but windows were broken in several houses, Sergei Aksyonov, the Russian-backed head of Crimea's administration, said on the Telegram messaging app.
He added that one unexploded drone was found on the territory of a residential house, forcing the temporary evacuation of about 50 people in the area.
Reuters could not independently verify the report.
Russia has a military air base near Dzhankoi. Ukrainian officials have long said the city and surrounding areas have been turned into Moscow's largest military base in Crimea.
