The Ukrainian army said on Sunday that Russia launched 15 drones on Ukraine, most of them in the south of the country overnight, and that air defenses destroyed 14 of them.

“As a result of air combat, Ukraine’s Air Force and defence forces destroyed 14 shaheds in Mykolaiv, Kirovohrad, Zaporizhzhia, Dnipro and Khmelnytskyi regions,” the Ukrainian Air Force said on the Telegram messaging app.

It added that the drones were launched from the eastern coast of the Sea of Azov in Russia.

Reuters could not independently verify the report. There was no immediate comment from Russia.

No damage or casualties have been reported by military and civilian authorities.
