Police in Italy say they’ve arrested a Ukrainian man suspected of coordinating the sabotage of three Nord Stream gas pipelines in 2022. The undersea explosions caused severe damage to infrastructure built to carry natural gas from Russia to Western Europe. The United States initially blamed the sabotage on Russia. German federal prosecutors have identified the suspect only as 49-year-old “Serhii K.” He’s allegedly part of a small team of Ukrainians who used a rented yacht, satellite navigation, sonar and seabed maps to plant timer-controlled explosives on pipelines on the bottom of the Baltic Sea.
