Russian forces have repelled separate Ukrainian drone attacks on the Moscow region and near Crimea, the Russian Defense Ministry said early on Sunday.
"Duty air defense systems destroyed two Ukrainian aircraft-type unmanned aerial vehicles (UAV) off the western coast of the Crimean peninsula," the ministry said in a notice without giving other details.
In the Moscow region, another Ukrainian aircraft-type UAV was destroyed over the territory of the Istrinsky district, the ministry added.
There was no damage or casualties at the site where the debris fell, according to Moscow Mayor Sergei Sobyanin.
Kyiv has not commented on the claimed attacks.
