KIEV, Dec. 8 - Ukraine's gas transport monopoly Ukrtransgaz said on Monday Russia would resume supplies of natural gas on Dec. 11 after a six-month gap due to a dispute over prices and unpaid debts, Reuters reported.

Without Russian gas and hit by separatist violence that has disrupted its own coal mining, Ukraine has been forced to introduce widespread power cuts.

The energy ministry had expected flows from Russia to resume on Monday. Hard frosts have boosted consumption to record volumes in recent weeks.
