Suggestions that Ukrainian authorities supported by Poland were behind planning and executing the sabotage attack on the Nord Stream gas pipelines in 2022 are groundless, the Polish president's aide said on August 18. Germany's former intelligence chief, August Hanning, told Die Welt this week that he believed there were agreements between the presidents of Poland and Ukraine to carry out the attack. But Mieszko Pawlak, head of the international policy bureau at the office of Polish President Andrzej Duda said the comments were “groundless insinuations.”
