Russian attacks have damaged at least 50% of Ukraine’s energy infrastructure. Officials in several regions of Ukraine, including Kyiv, reported power cuts after a new round of attacks on Tuesday hit energy facilities.

In the capital, energy operator DTEK said there were “interruptions” to the electricity and water supply to residents of the city’s left bank.

“Engineers are investigating and making all the necessary efforts to restore the power to the city’s residents,” the company said on Facebook.

Meanwhile, Russia has claimed to have hit military targets and energy infrastructure.
