German-led investigators examining the 2022 attack on Nord Stream gas pipelines are suggesting Poland may have served as a base for the operation, according to a Wall Street Journal report. The research points to a yacht, the Andromeda, that sailed into Polish waters before the sabotage, and had been traced via its radio and navigation equipment, satellite and mobile phones, and Gmail accounts. 

Key Points: 

1. The Nord Stream pipeline, a major conduit for gas from Russia to Germany, was sabotaged in 2022, a few months after Russia’s invasion of Ukraine.
2. The vessel purportedly used in the attack, the Andromeda, made an unusual detour into Polish waters, raising suspicions among German-led investigators about Poland’s potential involvement.
3. Investigative tools included tracking the Andromeda’s radio and navigation systems, as well as satellite and mobile phones, and Gmail accounts.
4. Earlier reports suggested Western intelligence agencies had foreknowledge of a Ukraine-backed plan to sabotage the pipelines, a claim Ukrainian President Volodymyr Zelenskyy strongly denied.
5. The explosive used in the sabotage, identified as HMX, is typically used for disrupting subsea infrastructure.
