MOSCOW (Reuters) - Russia's Gazprom gave Ukraine on Monday an extension into next week to resolve a gas price dispute at the heart of the two countries' confrontation, a day before Moscow was due to switch off the gas unless Kiev paid in advance.
The argument over prices for natural gas has quietly simmered in the background even as the two countries have squared off over Moscow's seizure of Ukraine's Crimea peninsula and over a pro-Russian rebel uprising in eastern Ukraine.
