The Swedish Coast Guard has found a fourth leak in the Nord Stream pipelines. The discovery was made earlier this week, a spokesman for the Swedish Coast Guard told the Swedish newspaper Svenska Dagbladet. The American channel CNN, meanwhile, reports, based on sources within the European intelligence services, that Russian naval ships were spotted near the Nord Stream 1 and 2 gas pipelines on Monday and Tuesday. The pipelines started leaking in three different places around that time.
