Explosion ‘like thunder’ at Pennsylvania US Steel plant leaves two dead

Second fatality reported after body of one worker pulled from wreckage of coking facility in Clairton after explosion sent black smoke into the sky

An explosion at a US Steel plant in Pennsylvania, near Pittsburgh, has killed two people and injured at least 10 on Monday, officials said.

The body of one worker was pulled from the wreckage hours after an explosion that sent black smoke spiraling into the sky in the Mon Valley, a region of the state synonymous with steel for more than a century. Allegheny county emergency services said a fire at the plant started around 10.51am. Authorities later said a second person had died.
