MOSCOW—An explosion during repairs on a section of a Europe-bound natural gas pipeline in western Russia killed three people on Tuesday but didn’t affect export supplies, officials said.
The explosion ripped through a section of the Urengoy-Pomary-Uzhhorod pipeline in the Chuvashia region during repair work. Three repair workers were killed and one was injured by the blast, which sent a huge plume of burning gas skyward, regional authorities said.
