Two Huge Gas Pipeline Explosions Rock The Russian Federation

An explosion on a main gas pipeline northeast of St. Petersburg, which further connects to Nord Stream 1, occurred over the weekend. Natural gas in Nord Stream 1 continued to flow.
In addition a second Gazprom pipeline erupted on Saturday morning 19 November at an apartment block on Sakhalin Island in Russia’s Far East. It as been reported that at least 9 people on Sakhalin were killed
No suggestion of sabotage has been mentioned and Russia’s Ministry of Emergency Situations said the explosion was likely the result of "depressurization" in pipeline, which officials have further reduced to stop the fire, Russian media outlet RIA reported.
If the pipe near St. Petersburg is put out of order, the entire "Nord Stream-1" may stop working, in the first place. It may cause problems with gas supplies to Finland.
