Russia, Ukraine and the European Union have reached a deal to resume the flow of Russian gas to Ukraine. The $4.6 billion accord ensures gas supplies until March, both for Ukraine and European countries on the receiving end of its pipelines. The gas will be paid for with help from the International Monetary Fund and what the European Commission called “unprecedented levels” of aid from the European Union. The deal comes amidst escalating tensions as pro-Russian separatists plan to hold elections Sunday in eastern Ukraine.
