(Reuters) - Ukraine's armed forces are introducing a new facet of air defence to transform their system, made up of small groups deploying interceptor drones, as the country braces for new mass Russian attacks, President Volodymyr Zelensky said on Monday 19 January 2026.

Ukraine is still reeling from a wave of Russian strikes earlier this month that knocked out power and heating to thousands of apartment blocks, particularly in the capital Kyiv.

Zelensky has repeatedly called for air defences to be strengthened, including increased assistance from Ukraine's Western allies.

"There will be a new approach to the use of air defences by the Air Force, concerning mobile fire groups, interceptor drones and other 'short-range' air defence assets," Zelensky said in his nightly video address. "The system will be transformed."

The president announced the appointment of a new deputy Air Force Commander, Pavlo Yelizarov, to oversee and develop the innovation.

Ukraine has rapidly developed its drone manufacturing system since Russia launched its invasion of its smaller neighbour in February 2022, and has emphasised interceptor drones as an effective and economical way to parry Russian strikes.

In his remarks, Zelensky warned Ukrainians to be "extremely vigilant" ahead of anticipated new Russian attacks.

"Russia has prepared for a strike, a massive strike, and is waiting for the moment to carry it out," he said, urging every region in the country to "be prepared to respond as quickly as possible and help people".

Both Zelensky and Foreign Minister Andrii Sybiha warned at the weekend that Ukrainian intelligence had noted Russia was conducting reconnaissance of specific targets, particularly substations that supply nuclear power plants.

The president also said he had instructed Prime Minister Yulia Svyrydenko to make decisions this week regarding difficulties from the recent attacks, including bonuses for tens of thousands of emergency crew members restoring heating and electricity.

(Reuters) - Russian forces launched a combined drone and missile attack on the Ukrainian capital of Kyiv early on Tuesday 20 January 2026, triggering cuts in power and water supplies, the city's mayor said.

Mayor Vitali Klitschko, writing on Telegram, said a strike on the east bank of the Dnipro River had disrupted both power and water supplies. A non-residential building had been hit and one person injured, he said.

Unofficial Telegram news channels posted photos of darkened high-rise apartment buildings.

Tymur Tkachenko, head of the capital's military administration, said a storage area had been damaged and several cars set ablaze.
