Russian firm Gazprom said Saturday that it was fulfilling European contracts after a German pipeline operator, Gascade, reported that flows via the Yamal-Europe pipeline from Russia through Poland had stopped, Reuters reports. Gazprom also signed a new five-year deal on supplies to Moldova, ending a potential energy crisis in the EU-aspirant state, amid earlier reports Russia had made political demands from Chișinău to water-down EU relations in return for fuel.
