Russia says Ukraine’s failure to pay its growing gas debt may impact gas delivery to European countries. Russia’s Energy Minister Alexander Novak said on Saturday that Moscow may be forced to cut off natural gas supplies to Europe over Ukraine’s mounting unpaid gas debt. According to Novak, Ukraine currently owes Russia over USD 2.230 billion in unpaid gas bills and the debt is to rise, as the figure does not include 1.3 billion for deliveries made in April. The Russian Energy Ministry also said Ukraine’s debt could lead to a situation where not enough gas would be pumped into Ukrainian underground storage facilities, which could then result in an undersupply of gas to Southeastern Europe.
