KYIV: Russia unleashed its second big attack on Ukraine`s energy infrastructure this month on Thursday, triggering deep power cuts across the country.

President Vladimir Putin said Moscow had struck in response to Ukraine`s strikes on Russian territory with US medium-range ATACMS missiles. He said Russia`s future targets could include `decisionmaking centres` in Kyiv.

Ukrainian President Volodymyr Zelensky accused Russia of a `despicable escalation`, saying it had used cruise missiles with cluster munitions.

Over one million people lost power in the immediate aftermath of the strikes, and millions more had their existing schedule of rolling power cuts intensified.Ukraine`s air force said Russia used 91 missiles and 97 drones in Thursday`s attack. It said 12 of those had hit their targets, most of which were energy and fuel facilities.

`The enemy is using a large number of missiles and drones.

Their massive use in certain areas often exceeds the number of means of (air defence) cover, the air force said in a statement.

Infrastructure facilities were damaged in nine regions, Ukraine`s Interior Ministry said. The attack reinforced fears of long power cuts during the winter months as temperatureshoveraroundzero.

Officials said it was the lith major strike on the energy system since March. Russia has knocked out about half Ukraine`s available generating capacity during the war, dam-aged the distribution system and forced authorities to impose long blackouts.

The air force said it had shot down 79 missiles and downed 35 drones, while 62 drones were `lost`, meaning it was likely they had been disrupted by ele ctronie warf are.

A source in the energy sector said Ukraine had disconnected all nuclear power units from the grid before the attack to protect them. Ukraine gets more than half of its electricity from nuclear plants.

Ukraine`s state grid operator Ukrenergo announced deep power cuts across the country because of damage from the attacks, warning of at least 12 hours without electricity for some consumers.

All missiles or drones aimed at the capital, Kyiv, were brought down, officials said.

The air force said Russia was using thermal and radar decoys to trick Ukrainian air defences, and putting electronic warfare devices on its missiles.

`All this significantly complicates the operation of Sovietmade anti-aircraft missile systems ... Western systems work much more effectively in such conditions, but Ukraine does not have enough to reliably cover hundreds of critical infrastructure facilities,` it said.

It said foggy weather conditions also made it harder for machine gunners to spot drones. More than 33 months after Russia invaded Ukraine, Russian ground forces are advancing at their fastest pace in two years.-Reuters
