A massive explosion has rocked the Amur Gas Chemical Complex in Russia’s Far East, leaving at least 7 people dead and more than 120 injured. The Russian-Chinese joint venture had been under construction for seven years and was designed to become one of the world’s largest polymer production facilities. The blast reportedly struck a methanol processing unit during the facility’s final pre-startup stage. Officials say the main equipment was not damaged and there is currently no threat to nearby residents.
