A nation with a decent tech capability either indigenous or purchased could get a ROV or AUS down 238 ft to plant an explosive any time in the last few months. Also, the explosion could have come from an internal explosion. It’s still sabotage but it become more complicated who was initiating the detonation, and for want reasons.
there will be a need to see the sites to confirm by a more neutral party otherwise no one will accept the findings. I still think any resolution will not be accepted.
There were 4 (FOUR) explosions that happened on 2 pipelines, KM apart.
(2 charges on each pipeline, standard military “one is none” redundancy SOP).
