Russian natural gas supplies to Germany have been halted for annual maintenance work. But the German economy minister warned that EU countries must be prepared for gas shipments not resuming, believing Russia is using gas ‘as a weapon’ in response to EU sanctions. Supplies to five European countries have already been cut over their refusal to comply with new payment schemes. Stopping supplying Germany could tip the country into a major recession. Entire industries rely on gas, and most German homes use it for heating. The head of the International Energy Agency has warned that Russia may cut off gas supplies to Europe entirely and that Europe needs to prepare now.
