Russia's paramilitary group Wagner threatened an urgent intervention in Russia's Belgorod province bordering Ukraine to settle what it called the chaos there, while Ukraine announced that the capital Kiev was subjected to new night rocket and drone attacks at dawn today.

Wagner owner Yevgeny Prigozhin said his forces would intervene to protect residents in Belgorod province if the defence ministry did not resolve what he called the chaos there soon.

Prigozhin stressed in an audio recording that his forces would not wait for permission from anyone to contain what he called the seizure of Russian territory.

Wagner forces withdrew days ago from the city of Bakhamut and handed them over to Russian forces after seizing them after months of fierce battles with Ukrainian forces.

Belgorod province has been targeted since the first month of Russia's war on Ukraine, and the frequency and quality of attacks has increased in recent weeks. The province is a major supply line for Russian forces inside Ukraine.

The governor of the province, Vyacheslav Gladkov, said the Ukrainian army on Sunday continued to bombard border villages and towns within the southwestern Russian province along Ukraine's northern border.

Gladkov said there was material damage to residential buildings and infrastructure in the town of Maslovu, between Belgorod and the Ukrainian border.

The Russian official said the shelling also led to a partial power outage in four Russian towns in the province. The governor of the province announced yesterday the suspension of transportation due to the seriousness of the situation.

Rocket attacks on Kiev

Meanwhile, military officials in the Ukrainian capital Kiev said Russia launched a new wave of air attacks on Ukraine on Sunday morning and that air defense systems repelled all missiles and drones as they approached Kiev.

The head of the city's military administration, Serhiy Popko, said on Telegram early in the day: "According to preliminary information, no air target has reached the capital. "The air defenses destroyed everything that was actually heading towards the city before arriving."

The military administration in Kiev said Russia attacked the Kiev region at dawn with rockets fired from the Caspian Sea and suicide bombers.

Russia has launched nightly rocket and drone attacks on the Ukrainian capital repeatedly since last month, ahead of a planned counteroffensive against Russia.

Dnipro, Donetsk and Crimea. Mutual attacks

In the centre of the country, the head of Dnipro's military administration, Serhiy Lesak, said 13 people were wounded in a Russian attack on the town of Podgoro-Deninskaya in the Dnipro region.

Lesak confirmed that work was underway to extinguish fires that broke out as a result of the attack, and that the attack destroyed a residential building. Ukrainian President Volodymyr Zelensky called the attack Russia's "new terrorist act" and vowed to hold Moscow fully responsible for its actions.

Moscow denies its military forces are targeting civilians, while photos posted on social media showed rescue teams working in a destroyed and burning building amid piles of shattered building materials.

In the context, the Russian military site Redovka said that Ukrainian forces targeted the city of Gorlovka, located in the Donetsk region, with thirty missiles, injuring a number of civilians and burning a residential building, according to the site.

Images posted by the website showed a fire in an apartment building and attempts by emergency services to deal with it.

In Crimea, which Moscow annexed from Ukraine in 2014, a Russian official said on Sunday a drone had been shot down in the Dzankoy region.

Oleg Kryuchkov said in a Telegram post that "there was damage to windows in several houses in one residential area" as a result of the overnight incident.
