Sabotage or accident? Nord Stream pipeline leaks raise alarm in Europe & Russia

Russia said that sabotage as a reason behind the reported leaks detected in Nord Stream gas pipelines cannot be ruled out. European countries are on a race to investigate the unexplained leaks in two Russian gas pipelines running under the Baltic Sea. Swedish authorities issued a warning about two leaks in Nord Stream 1 pipeline, shortly after a leak on the nearby Nord Stream 2 pipeline was discovered.
