Brussels - European Union energy ministers were meeting in Brussels on Monday to discuss ways of dealing with the shortage of Russian gas arriving via Ukraine.
The supply is now expected to resume on Tuesday following a deal on gas monitors signed in Brussels by representatives of Gazprom, Russia's state-owned gas monopoly, and Ukraine's Naftogaz, whose pipelines are used by Moscow to deliver gas to Europe.
But the long-standing dispute between the two sides has already forced many European countries to dig into their reserves.
It has also sparked a row between Slovakia and neighbouring Austria over Bratislava's plans to meet its own shortfall by re-opening a Soviet-era nuclear reactor shut down by the EU for safety reasons.
