On Saturday, the Washington Post published an article in which they point to Roman Chervinskyi, a colonel in Ukraine's special forces with "deep ties to the intelligence services", as the coordinator of the sabotage of Nord Stream 1 and 2 just over a year ago.

According to "people familiar with his role," he allegedly handled the logistics for a group of six people, the two media houses report. The group led by Chervinskyi allegedly rented a sailboat under false identities and then used deep-sea diving equipment to place explosive material on the two gas pipelines.

Didn't act on my own

Chervinskyi is not said to have acted on his own, nor is he said to have planned the operation. The colonel is said to have taken orders from senior Ukrainian officials, who finally reported to Ukraine's commander-in-chief Valery Zaluzhny.

Chervinskyi denies the allegations

"All speculation about my involvement in the attack on Nord Stream is spread by Russian propaganda without any basis whatsoever," Chervinskyi said in a joint response to the Washington Post and Der Spiegel.

Currently, the Ukrainian colonel is in prison in Kyiv on charges of acting without permission in another operation that tried to get a Russian pilot to go over to Ukraine.
