Ukraine has launched a new wave of drone attacks as Russians head to a presidential election expected to be won by Vladimir Putin.
The Russian Defense Ministry says 35 Ukrainian drones were shot down overnight, including four in the Moscow region.
Moscow Mayor Sergei Sobyanin said a fifth drone, near Domodedovo Airport, was shot down on Sunday morning. There are no reports of casualties or damage.
According to information from the Ministry of Defense, two more drones were shot down over the Kaluga region south of the Russian capital and the Yaroslavl region northeast of Moscow.
The attacks on the Yaroslavl region, located about 800 kilometers from the Ukrainian border, were some of the most far-reaching attacks Ukraine has launched so far.
Several Ukrainian drones were shot down over Belgorod, Kursk and Rostov regions bordering Ukraine and the southern Krasnodar region, the Defense Ministry said.
Belgorod Governor Vyacheslav Gladkov said that a 16-year-old girl was killed and her father was wounded in the Ukrainian shelling on Sunday.
The drone also fell on a refinery in the Krasnodar region, causing a fire that was extinguished a few hours later, according to regional authorities. A refinery worker died of a heart attack, officials said. Refineries and oil terminals were key targets of Ukrainian drone attacks.
The attacks followed a series of other Ukrainian drone strikes and other attacks in the past few days that Putin described as an attempt by Ukraine to terrorize residents and derail Russia's presidential election.
"Those hostile attacks have not and will not go unpunished," he said during a meeting of his Security Council on Friday.
Meanwhile, the Ukrainian military said 14 Russian drones were shot down over the Odesa region on Sunday. The attack followed a Russian ballistic missile attack on the southern port city on Friday that killed 21 people. A second missile then targeted the first responders on the scene, officials said.
As the war entered its third year, Russian forces gradually advanced on the front lines, while Ukraine retaliated with drone strikes inside Russia and border areas.
