Sawt Falasteen - Ukraine says Russia strikes power grid as more ground regained

Throughout the weekend Ukraine claimed new military successes against Russia's army in the east and south, the latest coming Sunday night when President Volodymyr Zelensky declared Izyum "liberated".

Moscow conceded having lost territory, and experts have said the confirmed recapture by Ukraine of the city would represent a serious blow to Moscow's military ambitions in east Ukraine.

Sunday evening the eastern region experienced widespread electricity blackouts, which Zelensky said deliberately hit civilian infrastructure. He blamed "Russian terrorists".

"A total blackout in the Kharkiv and Donetsk regions, a partial one in the Zaporizhzhia, Dnipropetrovsk and Sumy regions," Zelensky said in a statement on social media.

"No military facilities," he added. "The goal is to deprive people of light and heat."

Local Ukrainian authorities pointed to Russian strikes on their power infrastructure. Some districts reported later that power had been restored.

In Kharkiv region, a Russian strike on a power station killed one employee, Governor Oleg Synegubov said. He added that power had been partially brought back.

Ukraine's foreign ministry spokesman Oleg Nikolenko said the Russian attacks were an "act of desperation following Russia's immense losses and retreat in eastern Ukraine".

The Russian strikes hit 15 locations on Sunday, from Kramatorsk in the east to Mykolaiv in the south and Dnipro in between, Ukraine's military said.

Earlier, the bombardment of Pokrovsk, a city in the eastern Donetsk region, left six residents dead, Mayor Rouslan Trebouchkine said.

The blackouts hit regions with an estimated combined population of nine million people -- including territory controlled by Russia.

They came as Ukrainian forces claimed to have recaptured dozens of towns and villages in eastern Ukraine.

The Russian attacks were also disrupting railway services. Ukraine's national train service announced delays throughout the east including the country's second-largest city, Kharkiv.

Ukraine had already lost all power from the Russian-controlled Zaporizhzhia nuclear plant.

The country's nuclear energy agency said the final reactor at the plant, Europe's largest nuclear power station and a focal point of the conflict, had been shut off as a safety measure.

Russian President Vladimir Putin warned that Ukrainian attacks near the station could have "catastrophic consequences".

- 'Weapons, weapons, weapons' -

Sunday's address marked 200 days since the beginning of Russia's invasion.

The speed of Ukraine's fightback has apparently caught Russia's military off-guard, bringing swathes of territory Moscow had controlled for months back into Kyiv's fold.

Images posted by the Ukrainian military showed crates of munitions and military hardware scattered across territory abandoned by Russian forces.

In his evening address Sunday Zelensky praised the soldiers who had "liberated hundreds of our cities and villages... and most recently Balakliya, Izyum and Kupiansk".

Around Balakliya, one of the first towns to be retaken by Ukrainian troops, AFP journalists saw evidence of fierce battles, with buildings destroyed or damaged and streets mostly deserted.

Earlier Sunday, the head of the Ukrainian military announced that as much as 3,000 square kilometres (1,158 square miles) had been wrested from Russia since the offensive began at the beginning of this month.

The country's foreign minister used the momentum to appeal to Western allies for more stockpiles of sophisticated weapons.

"Weapons, weapons, weapons have been on our agenda since spring. I am grateful to partners who have answered our call: Ukraine's battlefield successes are our shared ones," Dmytro Kuleba said.

"Prompt supplies bring victory and peace closer," his statement on social media read.

- Russia 'regrouping' -

The reaction in Moscow to the Ukrainian gains so far has been muted, but on Sunday a military map presented by the Russian defence ministry showed that its forces had made a major withdrawal from the Kharkiv region.

Russia controlled just a sliver of territory in the region's east, behind the Oskil river, the revised map showed.

Russia's military made the surprise announcement Saturday that it was "regrouping" its forces from Kharkiv to the Donetsk region just south to focus its military efforts there.

That came shortly after Moscow said it was actually sending reinforcements towards Kharkiv.

The fresh fighting in and around the Zaporizhzhia plant has sharpened fears of another nuclear incident comparable to the Chernobyl disaster in northern Ukraine in 1986.

Putin, in a telephone call with French President Emmanuel Macron, once again accused Ukraine of repeated attacks on the facility held by Russian troops.

The Russian leader drew attention to "regular Ukrainian attacks" which could have "catastrophic consequences", the Kremlin said in a statement.

Each side has repeatedly blamed the other for shelling in the area.

Macron's office, in its summary of the conversation, said he had told Putin "the Russian occupation was the reason for the risks" facing the atomic power station.

In Balakliya, 52-year-old Iryna Stepanenko was outside cycling for the first time in months.

She had hidden in her basement for three months, she said, from the town that was home to about 27,000 people before the invasion.

But while she was relieved that Kyiv's forces were back, she still feared for the future.

"I'm worried the Russians could return. I'm worried the shelling could start again."
