Ukraine is dealing with the aftermath of another day of missile attacks, with power and water supplies still damaged in many locations after critical infrastructure was targeted by Russia. 

President Zelenskyy said in his nightly address Tuesday that, were it not for the additional strikes during the day, the Ukrainian authorities would have been able to focus on repairing and restoring water and energy supplies.

Ukraine’s energy system looked increasingly vulnerable on Wednesday after state nuclear energy company Energoatom said that a Russian missile attack had prompted a black-out at the Zaporizhzhia nuclear power plant in southern Ukraine. 

It said that the Russian-occupied facility was now running on diesel generators and alleged that Russian forces were blocking diesel deliveries to the plant.

Russia’s ramping up of missile strikes this week comes after it was dealt a blow last weekend when an explosion partially destroyed the Kerch Bridge that links the Russian mainland to Crimea, which Moscow illegally annexed in 2014. 

On Wednesday, Russia’s security services said it had made arrests in connection to the attack that was widely seen as humiliating for Moscow and President Vladimir Putin.

Kyiv has not said whether it was responsible for the attack on the bridge and said it would not respond to the arrests.
