Ukraine-backed group behind Nord Stream pipeline blast

The Nord Stream underwater gas pipeline in the Baltic Sea was blown up on 26 September 2022. Now the New York Times report says that the Ukraine-backed group was behind it. But no evidence has been found of the involvement of the Ukrainian government. Russia used to supply gas to Germany through this pipeline at cheap prices.
An American official was quoted in the New York Times as saying – no evidence has been found that President Volodymyr Zelensky or any of his associates were involved in blowing up the pipeline. There is also no evidence that he acted at the behest of the Ukrainian authorities. At the same time, Zelensky's Political Advisor said - We can say without any doubt that Ukraine had no hand in this.
NATO countries see the Nord Stream pipeline as a threat. It was like a boon for Germany. Through this, gas was being supplied to Germany at cheaper prices than Russia. However, the blast was attributed to Russia.
The blast in the Nord Stream underwater gas pipeline was condemned by the US and the North Atlantic Treaty Organization (NATO) countries. Russia blamed Western countries and demanded action. At the same time, American journalist Seymour Hersh also claimed that the pipeline was blown up secretly at the behest of US President Biden. However, no evidence was given.
Journalist Seymour Hersh reported that the bombing of the underwater gas pipelines was carried out by the CIA from Norway as part of a covert operation. Then in the deep sea, American divers blasted those pipelines by laying landmines around them. These claims were denied by the White House. White House spokeswoman Andrea Bester called the report false.
