On the second day of Russian airstrikes, a new round of Russian airstrikes targeted various areas in Ukraine, including vital energy infrastructure north of the Ukrainian capital, Kyiv, triggering multiple explosions, according to officials.

Kyrylo Tymoshenko, deputy head of the presidential office, stated on Tuesday that three Russian strikes had been launched against an unidentified energy plant. The mayor of Kyiv stated that the attack was on "critical infrastructure" and that emergency personnel was on their route.

Al Jazeera's Mohammed Jamjoom reported from Kyiv that the city is currently under air alert. "One went off this morning at 5 a.m. in Kiev, then it deactivated and another one began an hour and a half later," he explained.

The mayor of the northern city of Zhytomyr, Serhiy Sukhomlyn, said on Facebook that water and electrical supplies were cut off due to attacks.

On Tuesday, Ukrainian President Volodymyr Zelenskyy declared that Russian forces "continue to do what they do best: terrorize and kill civilians." He also stated that one person was killed in a missile attack on a residential building in the southern Ukrainian city of Mykolaiv, but he did not provide any other information regarding casualties.

"The occupiers are firing upon Ukraine," he tweeted on the Telegram messaging service.

"Such actions will not change anything for the terrorist state." It will simply reaffirm its deadly and destructive nature, for which it will be held accountable."

At least four people, including a couple expecting a child, were murdered when a drone struck a residential building in Kyiv the previous day. Hundreds of towns and villages were left without power as a result of the strikes.

The assaults on Monday occurred exactly one week after various Ukrainian cities were struck by Russian missiles and drones in apparent retaliation for the destruction of a crucial bridge connecting Crimea to the Russian mainland. Moscow has accused Ukraine of destroying the Kerch bridge, a crucial supply route for Russian forces battling in Ukraine.
