ISLAMABAD -- Iran has slapped Pakistan with a final notice to finish its part of a cross-border gas pipeline or face international arbitration, and possibly billions of dollars in fines.
Tehran's warning is the neighbors' latest flare-up over the long-delayed 1,900-kilometer (1,180-mile) pipeline, a project seen as critical to Pakistan's energy needs as its own proven gas reserves are set to run dry in a little over a decade.
