“This is a very dangerous situation, which requires an urgent investigation.”
Nato said in a statement: “All currently available information indicates that this is the result of deliberate, reckless, and irresponsible acts of sabotage.”

After the first leak was reported on 26 September by the Danish Maritime Authority, three more were reported, with two in Danish waters and two in Swedish waters.
Since then, Russia and the Western countries have been trading blame for the leaks.
The incident comes in the wake of the deepening conflict between Russia and the West over the former’s invasion of Ukraine.
The cause for the leaks is currently being investigated by the European Union (EU).
In a statement, the Nord Stream operator said: “Until the completion of the damage assessment, it is not possible to predict the time frame for restoration of the gas transmission infrastructure.”
