Russia said on Sunday it intercepted nine drones over the Crimean Peninsula and one over the small town of Sudzha in the southern region of Kursk, in what have been nearly daily attacks inside the country or on Moscow-held territories.
Five drones were shot down and four were jammed and did not hit their targets in Dzhankoi in Crimea, said a Russian-installed official in the peninsula that Moscow annexed from Ukraine in 2014.
A Ukrainian-launched drone was downed over Sudzha later in the day, the governor of the Kursk region that borders with Ukraine said on the Telegram messaging app.
Reuters could not independently verify the reports.
The strikes came after multiple attacks on the Russian border region of Belgorod and oil infrastructure inside the country, as well as a drone strike on wealthy districts of Moscow earlier in the week.
Kyiv denied attacking Moscow and Ukraine almost never publicly claims responsibility for attacks elsewhere inside Russia and on Russian-controlled territory in Ukraine.
There were no casualties in the Sunday drone attacks, officials said. In Dzhankoi, 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.
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.
