Russia, Ukraine clinch deal on winter gas supply

• Russia and Ukraine sign an agreement the parties say will guarantee the flow of Russian gas exports into Ukraine through the winter, following a long and bitter dispute over payments.
• European Union energy chief Guenther Oettinger, who brokered the deal, says "we can guarantee a security of supply over the winter," not only for Ukraine but also for the EU nations closest to the region that stood to suffer should the conflict in Ukraine worsen.
