A Ukrainian national charged in connection with the 2022 sabotage of the Nord Stream and Nord Stream 2 gas pipelines has admitted to serving in the Ukrainian armed forces and working for the Security Service of Ukraine (SBU) at the time of the attack, according to a report by German broadcaster N-tv, as cited by TASS.

Sergey Kuznetsov, who is being held in detention in Hamburg, made the admission during a monitored telephone conversation with his wife while in custody in Italy, according to an indictment filed by Germany's Federal Prosecutor's Office. The document, obtained by Stern magazine, contains several indications that Ukrainian state agencies were involved in the sabotage, though investigators reportedly hold only circumstantial evidence against Kuznetsov.

Coverage Comparison

TASS's reporting presents two distinct narratives. In one article, the focus is on Ukraine's official denial of involvement, as stated by the Ukrainian Prosecutor General's Office. The office said that based on investigative work so far, "no facts have been established that would indicate the involvement of the state of Ukraine, its authorized bodies, or officials in the commission of these unlawful acts," while acknowledging that the probe is ongoing.

The other TASS report highlights Kuznetsov's admission and the allegations of Ukrainian state agency direction, drawing on German media reports. Both articles reference the same core facts: the charging of Ukrainian national Sergey K., the use of the sailing yacht Andromeda, and the placement of explosive devices on the pipelines.

Key Claims

Germany's Federal Prosecutor's Office has filed charges against Ukrainian national Sergey K., suspected of participating in the sabotage of the Nord Stream and Nord Stream 2 pipelines.
Prosecutors believe that Kuznetsov and his accomplices developed the sabotage plan at the direction of Ukrainian state institutions.
According to investigators, the saboteurs used the sailing yacht Andromeda, chartered in Rostock, and divers attached explosive devices to the pipes on the seabed.
In monitored conversations while in Italian custody, Kuznetsov complained of feeling "abandoned" by his country and expressed a desire to speak with his "commander," a man named Roman, presumably Roman Chervinsky.
Chervinsky said in a written statement that Kuznetsov had been his subordinate at the time of the sabotage.
The Ukrainian Prosecutor General's Office stated that no facts have been established indicating the involvement of the Ukrainian state, its authorized bodies, or officials in the sabotage, while the investigation continues.

Perspectives

Ukraine's official denial

The Ukrainian Prosecutor General's Office has formally denied any state involvement in the sabotage, stating that no evidence has been found linking Ukraine, its government bodies, or officials to the attacks. The office emphasized that the investigation is not yet complete and that evidence collection is ongoing.

Allegations of Ukrainian state direction

Germany's Federal Prosecutor's Office alleges that Kuznetsov and his accomplices acted on behalf of Ukrainian state agencies. This view is supported by reported admissions from Kuznetsov, who said he was working for the SBU at the time, and by Roman Chervinsky's statement that Kuznetsov was his subordinate.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
