The Norwegian government has ordered increased surveillance to protect oil and gas infrastructure after Nord Stream pipelines were allegedly sabotaged this week, causing gas leaks into the Baltic Sea. Norwegian Prime Minister Jonas Gahr Store said that, "although there is no concrete threat," increased security is necessary. "We have a special responsibility as Europe's largest gas supplier," he explained at a press conference.The Nordic country's police are investigating the presence of drones near offshore installations, especially in September, and Norway has joined the sabotage thesis to assess the leaks in Nord Stream 1 and Nord Stream 2, which occurred within a narrow time frame. "The indications that it was a deliberate act are growing and it is a very serious situation," warned the prime minister, who sees it as "crucial" that Europe and NATO act "together" in the face of possible threats.Meanwhile, the origin of the possible leaks, preceded by explosions according to Sweden, continues to be investigated. In this regard, the UN Security Council will meet next Friday at Russia's request to discuss the leaks in the Nord Stream gas pipelines detected in the Baltic Sea, a diplomatic source told Efe agency today.Amid growing suspicions of possible sabotage, Moscow today requested an urgent session of the UN's highest decision-making body.Although Russia had hoped the meeting would take place tomorrow, Thursday, France - which this month holds the rotating presidency of the Security Council - has called it for Friday afternoon (New York time), according to the source.
