Dozens of Russian attacks have pounded Ukraine in recent weeks, causing repeated power cuts across the country. Ukraine's Energy Minister Herman Halushchenko said the attacks had damaged power generating facilities and said the situation was "difficult" in the Odesa and Kyiv regions.
The mayor of Lviv said on Thursday that 90% of his city was without power, while Mr Klitschko said that 40% of Kyiv had been left without power.
Power cuts were also reported in the Odesa and Dnipropetrovsk regions. บาคาร่า350
