Russian attacks on Ukraine over the past eight days have destroyed 30% of the country's power stations, causing "massive blackouts across the country," Ukrainian President Volodymyr Zelensky tweeted on Tuesday.
Driving the news: Russia has stepped up its attacks since Oct. 10, when Russian President Vladimir Putin ordered a missile bombardment on Kyiv and cities across Ukraine in retaliation for the explosion of a bridge linking mainland Russia with occupied Crimea — which Moscow blamed on Ukrainian forces.
