Ukraine stopped the flow of Russian natural gas to Europe on May 11 through the cross-border Sokhranivka station, blaming Russian-backed separatists of siphoning supplies. Gas TSO of Ukraine (GTSOU) reported the occurrence of force majeure, which makes it impossible to further transport gas through the Sokhranivka and the border compressor station (CS) Novopskov, which are

in the occupied territories. “CS Novopskov is the first compressor station of the Ukrainian GTS in the Luhansk region, through which almost a third of gas from Russia to Europe (up to 32.6 million cubic meters per day) is transited,” GTSOU said in a statement.
