Leak detected in major pipeline that brings Russian oil to Germany

An oil leak was detected on a pipeline in Poland that's the main route through which Russian crude reaches Germany, the pipeline's Polish operator said Wednesday.

The operator, PERN, said it detected a leak in the Druzhba pipeline on Tuesday evening that's 45 miles from the central Polish city of Plock. It said the cause of the leak wasn't known.

The incident follows leaks late last month in the Nord Stream 1 and 2 gas pipelines running along the Baltic seabed, and amid an energy standoff between Russia and the West over Russia's invasion of Ukraine. Denmark and Sweden say those natural gas pipelines were attacked with large amounts of explosives.
