He made the statement after a special energy coordination call with officials involved in emergency response, regional authorities, the military, and energy sector representatives.
Restoration work has already begun in all oblasts where strikes were recorded. The call also separately addressed the situation in Dnipropetrovsk, Zaporizhzhya, Sumy, and Chernihiv oblasts, as well as in Odesa.
Air Force Commander Lt. Gen. Anatolii Kryvonozhko reported on the use of air-defense systems to intercept Russian missiles and presented initial findings on the enemy’s updated strike tactics.
“I instructed the military to immediately contact our partners — first and foremost the United States — and provide them with detailed information about Russia’s change in strike tactics and its targeted focus on energy facilities,” Zelenskyy wrote.
The president said work on requests for air-defense missiles will continue, as time is critical for every request and every delivery element. He also said Interior Minister Ihor Klymenko reported that fires at affected facilities had been extinguished and that reserve equipment is available for the capital.
Zelenskyy added that at least some of the missiles used by Russia in the Jan. 20 attack were manufactured this year.
“This once again shows how important it is that global sanctions against Russia and the blocking of critical components truly work,” he wrote.
The president instructed Prime Minister Yuliia Svyrydenko and Energy Minister Denys Shmyhal to provide a full regional recovery timeline and resource assessment by 6 p.m. Tuesday.
In the combined overnight attack on Ukraine on Jan. 20 (starting at 7 p.m. on Jan. 19), Russian forces launched 34 missiles and 339 strike drones, including Shahed, Gerbera, Italmass, and other UAV types. Of those, 250 were Shahed drones.
Russia carried out mass strikes on Kyiv and other Ukrainian cities. Hits were recorded in Odesa, Vinnytsia, Rivne, and Kyiv oblasts. Zaporizhzhya and Dnipro were also under attack.
Strikes targeted critical and energy infrastructure as well as industrial facilities. Ukrenergo reported that emergency power outages were introduced in several regions.
On the Kyiv's left bank, residents reported disruptions in electricity and water supply.
On Jan. 20, due to the severe energy situation after the Russian attack, Kyiv changed metro operations. Mayor Vitaly Klitschko said that 5,635 apartment buildings were left without heating. Nearly 80% of them were buildings where heating had only recently been restored after Jan. 9.
In Kyiv Oblast’s Bucha district, a man was killed as a result of the Russian attack.
