Russia halting gas supplies to Ukraine
Russia's state-controlled gas company is halting supplies to Ukraine.
Gazprom chief executive Alexei Miller said Russia sent the last shipment to Ukraine at 10am local time on Wednesday and would not send more because Ukraine has not paid for future supplies.
Russia resumed gas shipments to Ukraine less than two months ago after the two countries signed an EU-brokered deal ensuring supplies through March.
Past gas disputes between Russia and Ukraine have led to cut-offs. One stand-off in 2009 caused serious disruptions in shipments to EU countries in the dead of winter.
Temperatures in Ukraine, where most homes rely on piped gas for central heating, were below freezing on Wednesday morning.
