Intelligence agencies in the United States have suggested that a pro-Ukrainian group was responsible for sabotaging the Nord Stream pipelines, which transport natural gas from Russia to Europe. The Ukrainian government, however, has denied its involvement in the attack.

The incident, which occurred earlier this week, caused a major disruption to gas supplies, leading to concerns about the stability of the European energy market. Reports indicate that one of the pipelines was hit by an explosion, leading to a fire and the shutdown of the facility.

While initial reports suggested that the attack could have been carried out by Russian operatives, intelligence officials now believe that a Ukrainian group was responsible. According to reports in the New York Times, the group in question had been operating in the area and had a motive to disrupt the pipelines.

The German government, which is heavily reliant on gas supplies from Russia, has expressed caution over the incident. Some officials have called for an independent investigation to determine who was responsible for the attack.

Meanwhile, Ukraine has reiterated its denial of any involvement in the sabotage. In a statement, the government said that it was committed to maintaining good relations with both Russia and its European neighbors.

The incident has sparked renewed debate about the Nord Stream pipelines, which have long been a divisive issue in Europe. Some countries, particularly those in Eastern Europe, have expressed concerns about their reliance on Russian gas and the need to diversify their energy sources.

As of now, it remains unclear who was responsible for the attack on the pipelines. The investigation into the incident is ongoing, and officials are expected to release more information in the coming days.
