Zelensky seeks air defences amid Kyiv freeze

Ukrainian President Volodymyr Zelensky sought more air defence support from allies on Sunday as hundreds of buildings in Kyiv were without heating in freezing temperatures for a second day after Russian strikes.

Russia has hit Ukrainian energy infrastructure throughout the nearly four-year war, but Kyiv says this winter has been the toughest, with hundreds of Russian drones and missiles overwhelming air defences during particularly fierce frosts.

"This week alone, the Russians have launched more than 1,700 attack drones, over 1,380 guided aerial bombs, and 69 missiles of various types," Zelensky said as he arrived in Vilnius.

"That is why missiles for air defence systems are needed every day, and we continue working with the United States and Europe to ensure stronger protection of our skies," he added.

Russian bombardments have hit Kyiv particularly hard, forcing half a million people to evacuate.

"There are currently 1,676 high-rise apartment buildings in Kyiv without heating following the enemy's attack on Kyiv city on January 24," said mayor Vitali Klitschko.

Sub-zero temperatures and repeated air strikes have slowed efforts by repair crews working to restore heating and electricity.

In Vilnius, Zelensky was taking part in a ceremony to commemorate the 1863 uprising in Poland and Lithuania against Tsarist Russia.

Polish President Karol Nawrocki, who also attended the event, drew a parallel between the Russian invasion of Ukraine and past struggles for freedom by peoples in the Russian empire.

"The message of these celebrations is that by looking to the past for what we have in common, it's easier today to face the problems ahead of us. Especially in an era of the revival of imperial Russia," his office said on X.
