Multiple explosions at a US Steel plant near Pittsburgh killed at least one person and injured 10 others, authorities said yesterday, and emergency crews were searching through the rubble for an employee believed to be missing.
The blasts at the Clairton Coke Works – part of a sprawling industrial complex along the Monongahela River – took place just before 11am ET (1500 GMT). There was no word yet on a possible cause of the explosion.
