Ammon News - Russia's air defences destroyed 77 Ukrainian drones launched overnight, Russia's defence ministry said on Sunday, as both sides continue cross-border air attacks in the nearly four-year-old war.

The drones were downed over seven regions in southern and central Russia and over Russian-annexed Crimea, the ministry said in a statement on the Telegram messaging app.

A power transmission tower was damaged in the Rostov region bordering Ukraine about 1,000 km (620 miles) south of Moscow, leaving about 250 residents without electricity, Rostov Governor Yuri Slyusar said on Telegram, adding that no one was injured.

Forty-two drones were destroyed over the Saratov region in southwestern Russia and 12 over the Rostov region, the defence ministry said.
