Ukraine says ‘massive’ Russian attack targeted energy infrastructure

Kyiv (CNN) — Russia carried out a “massive attack” on Ukraine’s energy infrastructure, top Ukrainian officials said early Friday, killing at least one person and leaving parts of the capital Kyiv without power.

The Kremlin appears again to be using a tactic deployed in previous years, depriving Ukrainians of power and heat ahead of the bitter winter months. Russia started attacking Ukraine’s energy infrastructure in late September, according to official reports and CNN’s assessment.
