Hundreds of drones and missiles struck Kiev and Kharkiv overnight, knocking out power to thousands of homes.

Russian troops attack energy infrastructure in Ukraine’s capital Kiev and its second city Kharkiv Assuming a week-long truce According to Ukrainian officials, winter conditions have ended.

Ukraine’s Foreign Minister Andry Sibiha said on Tuesday that Russia had been attacked by 450 drones and more than 60 missiles overnight, accusing Moscow of waiting for temperatures to drop before re-targeting energy infrastructure under harsh sub-zero conditions.

U.S. President Donald Trump said last week that Russia had agreed to suspend attacks on Ukrainian cities amid the cold weather. Since launching a full-scale invasion of Ukraine in February 2022, Moscow has concentrated its firepower on Ukraine’s energy infrastructure every winter.

Artillery attacks on Tuesday injured at least two people in the capital and two others in the city of Kharkiv, officials said.

Kiev Mayor Vitali Klitschko said 1,170 residential buildings in the capital were without heating as temperatures dropped to -17 degrees Celsius (1.4 degrees Fahrenheit).

Tymur Tkachenko, the head of Kiev’s military administration, said in a telegram that Russia “launched another large-scale attack on Kiev in the freezing cold” overnight, urging residents to stay in shelters.

He said the attacks affected five urban areas, causing damage to three apartment buildings and a kindergarten building.

Videos on social media showed flames engulfing the upper floors of an apartment building in the capital.

According to unconfirmed media reports, two thermal power plants in the capital were attacked.

“Maximum damage”

Russian attacks on energy infrastructure have knocked out heating and electricity in hundreds of residential areas in Kiev and other Ukrainian cities in recent weeks.

Kharkiv Mayor Ihor Terekhov said Tuesday’s attack was aimed at “causing maximum damage… and depriving the city of heat during a severe frost”.

He said that as a result of the attacks, officials had to cut heat to 820 buildings to drain coolant and prevent the wider network from freezing.

Public broadcaster Suspilne said the attacks knocked out power in the towns of Izyum and Balakliya in the Kharkiv region and hit two apartment buildings in the northern city of Sumy.

Ivan Fedorov, the military administrator of the southeastern city of Zaporizhia, said on Telegram that a 38-year-old woman was killed in a drone strike in the suburbs.

The so-called truce failed

Trump announced Thursday that Russian President Vladimir Putin had agreed to his personal request to halt attacks on “Kiev and multiple towns” during the harsh winter months.

Moscow said it had agreed to the request but said the truce would only last until Sunday and did not link the measure to cold temperatures.

Kyiv welcomed the move and said the truce was scheduled to last for a week from January 30, but reports suggested Moscow was continuing to launch attacks.

The attack comes as Russian and Ukrainian officials prepare for talks. A new round of negotiations brokered by the United States Wednesday in Abu Dhabi.

“Neither Abu Dhabi’s expected diplomatic efforts this week nor (Putin’s) commitment to the United States have deterred him from continuing his campaign of terror against ordinary people in the harshest of winters,” Sibiha wrote on social media.

Ukrainian President Volodymyr Zelensky said Russia was prioritizing more attacks over peace talks.

“It is more important for Russia to use the coldest days of winter to scare its people than to resort to diplomacy,” Zelensky wrote on social media.

Zelensky said on Monday that the recent “de-escalation of tensions” with Russia would help build trust in negotiations.
