Russia's Gazprom has told customers in Europe it cannot guarantee gas supplies because of 'extraordinary' circumstances, Report informs, citing Reuters.
Known as an 'act of God' clause, force majeure is standard in business contracts and spells out extreme circumstances that excuse a party from their legal obligations.
Uniper, Germany's biggest importer of Russian gas, was among the customers who said they had received a letter, and that it had formally rejected the claim as unjustified.
A trading source, asking not to be identified because of the sensitivity of the issue, said the force majeure concerned supplies through the Nord Stream 1 pipeline, a major supply route to Germany and beyond.
Already on June 14, Gazprom had cut the pipeline's capacity to 40%, citing the delay of a turbine being maintained in Canada by equipment supplier Siemens Energy.
