Air force needs to improve its response to Russian drone attacks: Zelenskyy

Ukrainian President Volodymyr Zelenskyy on Friday described the performance of the air force in parts of the country as "unsatisfactory," and said that steps are being taken to improve the response to large-scale Russian drone barrages of civilian areas.

The repeated Russian aerial assaults have in recent months focused on Ukraine's power grid, causing blackouts and disrupting the heating and water supply for families during a bitterly cold winter.

With the war about to enter its fifth year later this month following Russia's all-out invasion of its neighbour, there is no sign of a breakthrough in US-led peace efforts following the latest talks this week. Further US-brokered meetings between Russian and Ukrainian delegations are planned "in the near future, likely in the United States," Zelenskyy said.

Zelenskyy on Friday said he had discussed with his defence minister and the air force commander what new air defence measures Ukraine needs to counter the Russian barrages. He didn't elaborate on what would be done.

Russia fired 328 drones and seven missiles at Ukraine overnight and in the early morning, the air force said, claiming that air defences shot down 297 drones.

One person was killed and two others were injured in an overnight Russian attack using drones and powerful glide bombs on the central Dnipropetrovsk region, according to the head of the regional military administration, Oleksandr Hanzha.

A Russian aerial attack on the southern Zaporizhzhia region during early daylight hours injured eight people and damaged 18 apartment blocks, according to regional military administration head Ivan Fedorov.

A dog shelter in the regional capital was also struck, killing 13 dogs, Zaporizhzhia City Council Secretary Rehina Kharchenko said.

Some dogs were rushed to a veterinary clinic, but they could not be saved, she said. Seven other animals were injured and are receiving treatment.

Amid icy conditions in Kyiv, more than 1,200 residential buildings in multiple districts of the capital have had no heating for days due to the Russian bombardment of the power grid, according to Zelenskyy.

The UK defence ministry said on Friday that Ukraine's electricity network "is experiencing its most acute crisis of the winter."  Mykola Tromza, an 81-year-old pensioner in Kyiv, said he has had his power restored, but recently went without heating and water at home for a week.

"I touched my nose and by God, it was like an icicle," Tromza said. He said he ran up and down to keep warm.

Russia's Defence Ministry said that air defences downed 38 Ukrainian drones overnight, including 26 over the Bryansk region.

Bryansk Gov Alexander Bogomaz said the attack briefly cut power to several villages in the region.

Another Ukrainian nighttime strike damaged power facilities in the Russian city of Belgorod, disrupting electricity distribution, Gov Vyacheslav Gladkov said.

Local reports said that Ukrainian missiles hit a power plant and an electrical substation, cutting power to parts of the city.

Fierce fighting has also continued on the front line despite the frigid temperatures.

Ukraine's Commander in Chief, Col Gen Oleksandr Syrskyi, said the front line now measures about 1,200 kilometres in length along eastern and southern parts of Ukraine.

The increasing technological improvements to drones on both sides mean that the so-called "kill zone" where troops are in greatest danger is now up to 20 kilometres deep, he told reporters on Thursday in comments embargoed until Friday.
