Ukraine says situation 'critical' after strikes on energy facilities

The situation in Ukraine is "critical" following waves of Russian strikes targeting the country's energy infrastructure ahead of winter, Ukraine's presidency said Tuesday.

"The situation is critical now across the country because our regions are dependent on one another... it's necessary for the whole country to prepare for electricity, water and heating outages," Kyrylo Tymoshenko, the deputy head of the Ukrainian president's office, told Ukrainian television.
