Kazakhstan held nationwide mourning on Sunday after 45 people died in a fire at an ArcelorMittal mine, the worst accident in the central Asian country’s post-Soviet history.

The tragedy, which struck at the Kostenko coalmine in the Karaganda region on Saturday, came after a series of deadly incidents at ArcelorMittal mines and has prompted the nationalisation of the company’s local affiliate.
