Baltic Sea, off the southern tip of Sweden. The Nord Stream 1 and Nord Stream 2 gas pipelines, which supply gas from Russia to Europe, began leaking massive quantities of gas three times on the same day, causing it to rise violently to the surface. Later, the Swedish and Danish seismological institutes identified three separate underwater explosions. An investigation by the Washington Post in November 2023 identified Ukrainian Colonel Roman Chervinsky as the possible culprit. He allegedly managed the logistics and support of a six-man team sent to the Baltic with a sailboat and scuba gear to plant explosive charges on underwater structures. Chervinsky had reportedly always responded, at least indirectly, to the orders of Valery Zaluzhny, general in charge of the Ukrainian army.
