Nord Stream 1: How Russia is cutting gas supplies to Europe
Russia has completely halted gas supplies to Europe via a major pipeline, saying repairs are needed.
The Nord Stream 1 pipeline stretches 1,200km (745 miles) under the Baltic Sea from the Russian coast near St Petersburg to north-eastern Germany.
It opened in 2011, and can send a maximum of 170 million cubic metres of gas per day from Russia to Germany.
The pipeline was shut down for 10 days in July - again for repairs, according to Russia - and has recently been operating at just 20% capacity because of what Russia describes as faulty equipment.
The president of Germany's network regulator has said the country will be able to cope - if Russia resumes delivery in the coming days
German Economy Minister Robert Habeck told the Financial Times that the move has already forced some German companies to stop production, a development he said was "alarming".
European leaders fear Russia could extend the outage in an attempt to drive up gas prices, which have already risen sharply in the past year.
