HARRISBURG, Pa. (AP) — The fatal explosion last week at U.S. Steel’s Pittsburgh-area coal-processing plant has revived debate about its future just as the iconic American company was emerging from a long period of uncertainty.

Two people were killed and 10 others were injured in an explosion at the U.S. Steel Clairton Coke Works plant on Monday.
