Nord Stream leak: West shores up pipeline security, blaming Russia 'sabotage'

European countries say they will ramp up security around oil and gas installations after the suspected sabotage of two major pipelines.

The EU, US and Nato have suggested damage to the pipelines between Russia and Germany was deliberate, but have not blamed Russia directly.

Russia has said it was not involved, and asked if the US was instead.

Russia has previously been accused of using gas supplies as a weapon against the West over its support for Ukraine.

The leaks on the Nord Stream 1 and Nord Stream 2 pipelines were discovered on Monday and Tuesday.

Neither pipeline was operating at the time, as the Nord Stream 2 project was abandoned when Russia invaded Ukraine, and Russia shut down Nord Stream 1 in September, citing a need for maintenance.
