“北溪”天然气管道从俄罗斯出发，经波罗的海海底抵达德国。2022年9月26日，“北溪”管道发生爆炸，大量天然气泄漏。调查发现，4条管道中的3条发生泄漏，共有4个泄漏点，位于瑞典和丹麦附近海域。

西科尔斯基没有说“北溪”管道遭谁破坏。2022年9月，身为欧洲议会议员的西科尔斯基暗示这一事件与美国有关，在社交媒体发布“北溪”管道遭破坏的图片，配文“谢谢你，美国”。不过，他数小时后删除这条帖文。此外，西科尔斯基还提及美国总统约瑟夫·拜登曾经威胁要破坏“北溪”管道。

“北溪”管道遭破坏事件发生后，丹麦、瑞典和德国分别启动调查，但拒绝俄罗斯参与。今年2月，瑞典、丹麦相继宣布结束调查，但对调查结论讳莫如深。

The Nord Stream gas pipeline runs from Russia to Germany under the Baltic Sea. On September 26, 2022, the Nord Stream pipeline exploded and a large amount of natural gas leaked. The investigation found that three of the four pipelines were leaking, with a total of four leakage points, located in the waters off Sweden and Denmark.

Mr. Sikorski did not say who had damaged the Nord Stream pipeline. In September 2022, Sikorski, a member of the European Parliament, hinted that the incident was linked to the United States, Posting pictures of the destruction of the Nord Stream pipeline on social media with the caption "Thank you, America." However, he deleted the post a few hours later. Sikorski also mentioned that US President Joseph Biden had threatened to sabotage the Nord Stream pipeline.

Denmark, Sweden and Germany launched separate investigations after the sabotage of the Nord Stream pipeline, but refused to allow Russia to participate. In February this year, Sweden and Denmark announced the end of the investigation, but the conclusion of the investigation is very secretive.
