MOSCOW/BERLIN (Reuters) – Russia denied on Saturday a German media report suggesting that it could sign a gas pipeline deal with Greece as early as Tuesday which could bring up to five billion euros into Athens’ depleted state coffers. German magazine Der Spiegel, citing a senior figure in Greece’s ruling Syriza party, said the advance funds could “turn the page” for Athens, which is now struggling to reach a deal with its creditors to unlock new loans to avert bankruptcy.
