> On 6 June 2023, The Washington Post reported that an intelligence agency of an unnamed European "close ally" had notified the CIA of a Ukrainian military plan for a covert attack on the pipeline. The plan was to be carried out by a team of divers reporting to Gen. Valery Zaluzhny, commander-in-chief of the Ukrainian armed forces, but the Post did not report any evidence that it had been put into action. The US reportedly learned of the plan three months before the destruction of the pipeline, and shared the intelligence with Germany and other allies.

Yes it must be obvious for Ukraine to use people who are already in Russia to help with local sabotage. It could be as as crude as putting rocks on a rail line or as simple as floating toy balloons across a strategic installation until the local Russian defenses get tired of the false alarms, stop paying attention and don't see an incoming drone.
It's surprising that there are apparently no strong claims of this from either side, but especially from the Russian side. I don't agree that Russia has nothing to gain from arresting people for such activities. Wouldn't it deter others?
