On Friday, Russia hit numerous regions in Ukraine with the heaviest rocket attacks in weeks.

Many areas reported power outages.

It is still unclear how extensive the damage is.

However, some Ukrainian energy suppliers are already saying that the output of the power grid has been roughly halved.

According to Ukrainian media, the water supply is said to have failed in some cases.

In the capital Kyiv and elsewhere, civilians went into shelters after air alerts were declared across most of the country.

When the anti-aircraft defenses were deployed, there were explosions in Kyiv.

Mayor Vitali Klitschko confirmed the attacks in the Telegram news service and called on people to seek protection.

The metro in the capital shut down traffic and served as a bunker.

Light, water and heating failed in Kyiv, as a reporter from the German Press Agency reported from the three-million metropolis.

The media spoke of around 70 rocket attacks on Ukraine.

Numerous regions reported rocket fire, including Zaporizhia, Mykolaiv, Vinnytsia, Poltava, Dnipropetrovsk and Kharkiv.

Accordingly, Russia again specifically targeted the energy infrastructure.

In the south-eastern Ukrainian industrial city of Kryvyi Rih, authorities said two people were killed as a result of the rocket attacks and five were injured when a house was hit.

One of the worst attacks since October

The presidential administration in Kyiv announced that the nationwide switch to emergency energy supply was in progress.

She called on people, who often sit in the cold and darkness, to understand the attacks that have been going on for weeks.

There are places of protection and warmth in the country where they could go.

Emergency services would also work to repair the hit and damaged power plants.

Energy Minister Herman Halushchenko confirmed hits on energy infrastructure objects in the south and east of the country.

"There are emergency power cuts," he wrote on Facebook.

It was one of the most severe attacks since Russian attacks on the country's energy infrastructure began on October 10.

The Russian-occupied areas of Ukraine also reported rocket fire.

In the town of Lantratowka in the Luhansk region, eight people were killed by fire from the Ukrainian side and 20 people were injured, the authorities there said.

The information could not be verified by an independent party.

Selenskyj demands tanks again

Ukrainian President Volodymyr Zelenskyy has urgently called on the EU states to supply modern tanks and anti-aircraft defenses for the defense against Russia.

In a video address at the Brussels summit on Thursday, he also asked leaders for large-scale gas and electricity supplies to compensate for the destruction of infrastructure by Russian attacks.

"I ask you to show leadership," Zelenskyj said.

"The one who will be the first to deliver modern tanks will open up the possibility of deliveries from all over the world and will be remembered as one of the greatest defenders of freedom of our time." There is no rational reason why Ukraine cannot deliver the tanks at this time should get.

The same applies to long-range artillery and missile systems, which could hasten the end of Russian aggression.

"All of this would mean a direct saving of millions of lives."

Ukrainian army chief demands 300 tanks and 500 howitzers for victory

The Ukrainian commander-in-chief, Valeriy Zalushnyi, also requested new weapons for a victory over the Russian army.

"I need 300 main battle tanks, 600 to 700 infantry fighting vehicles and 500 howitzers," said the 49-year-old in an interview with the British magazine "The Economist".
