Norway's military said on Monday it had posted soldiers to help guard major onshore oil and gas processing plants, part of a wider effort to boost security amid suspicion that sabotage caused leaks in the Nord Stream gas pipelines last week.
Russia's Nord Stream 1 and 2 pipelines burst on Sept. 26, draining gas into the Baltic Sea off the coast of Denmark and Sweden. Seismologists registered explosions in the area, and police in several countries have launched investigations.
Norway, Europe's largest gas supplier and a major oil exporter, last week deployed its navy and air force to patrol offshore petroleum fields and announced it would receive assistance from Britain, Germany and France in doing so.
