“The damage to the Nord Stream 1 and Nord Stream 2 pipelines in the international waters of the Baltic Sea is a matter of deep concern.
All information currently available indicates that this is the result of deliberate, reckless and irresponsible acts of sabotage,” the statement said.
The Alliance has expressed concern that leaks pose risks to shipping and damage the environment.
NATO has declared its readiness to respond to any deliberate attack on the critical infrastructure of the allies.
Earlier, the Russian embassy in the United States said that Russia insists on an objective investigation of the Nord Stream incident.
According to Swedish Foreign Minister Ann Linde, the incidents with gas leakage occurred as a result of explosions.
The locations of physical damage to both Nord Stream lines have been identified and are located in the exclusive economic zone of Denmark and Sweden.
It is impossible to estimate the timing of the resumption of the operation of the gas pipeline.
