It's from one side at the moment.
But I still remember the early days Russians denied the MH-17 shooting but eventually all evidence can point to Russia, however with no way to pass a tribunal given Russia's veto in the UN.
Believe me, I don't trust Putin. I just don't see from Russia's perspective how destroying the pipeline makes any sense. They were in the perfect position having the ability to control the flow to their benefit.
