Ukraine war: Russia to keep key gas pipeline to EU closed

Russia's main gas pipeline to Europe will not reopen as planned on Saturday, adding to concerns about energy supplies this winter.

State energy firm Gazprom said it found a leak on Nord Stream 1, meaning it could be closed indefinitely.

The pipeline, which runs to Germany, has been shut for three days for what Gazprom described as maintenance work.

Europe accused Russia of using its gas supplies to blackmail Europe amid the Ukraine conflict, which Moscow denies.
