"The enemy once again used its drones against Kyiv overnight!" Serhiy Popko, head of Kyiv's military administration, said on the Telegram messaging app. "Russian drones entered the capital of Ukraine in several waves and from different directions."

All the air weapons were destroyed on their approach and, according to preliminary information, there were no reports of damage or injuries, Popko said. Details regarding the size of the attack will come later in the day, he said.

Oleksandr Prokudin, governor of the southern region of Kherson, said early on Sunday on Telegram that one civilian had died and 15 were injured in Russia's attacks on the region in the past 24 hours.

Both sides deny targeting civilians in the war, which Russia launched with a full-scale invasion of its smaller neighbor in February 2022. But thousands of civilians have died, the vast majority of them Ukrainians.
