Almost 2 million people have been hit power cuts in Crimea, a Ukrainian peninsula annexed by Russia in March 2014.
All four of the main power lines running through the mainland Kherson region of Ukraine have been knocked down. The first two were heavily damaged on Friday, and the second two were blown up on Sunday shortly after midnight plunging the disputed peninsula into darkness overnight and prompting a state of emergency there. Crimean Tatar activists, denying repair workers access to the damaged power lines, suggested that the weakened pylons were blown down by the wind. But Ukraine's state energy company, Ukrenergo, said the damage was caused by "shelling or the use of explosive devices". Reports in Ukraine said that the police had clashed with activists from Right Sector movement in the area on Saturday after the initial damage. The government in Crimea imposed rolling blackouts on most residential neighborhoods and announced that it had enough fuel on hand for emergency generators to keep them running for a month. Crimea announced a day off for nongovernment workers on Monday, and shut down public services that use a lot of electricity, like the trolley-bus service in the port city of Sevastopol, replacing it with regular buses on some routes. Only 30% of Crimea's electricity is generated locally - the rest comes from Ukraine.
