On 26 September 2022, a series of underwater explosions and consequent gas leaks occurred on 3 of 4 pipes of the Nord Stream 1 (NS1) and Nord Stream 2 (NS2) natural gas pipelines, two of 23 gas pipelines between Europe and Russia. Both pipelines were built to transport natural gas from Russia to Germany through the Baltic Sea, and are majority owned by the Russian majority state-owned gas company, Gazprom.
