Johannesburg - Shares of ArcelorMittal slump more than 3 percent after the South African arm of the world's largest steel producer reports a widening of its full-year loss.

ArcelorMittal's South African operation has posted a 2012 headline loss per share of 129 cents, compared with a headline loss per share of 13 cents in the previous year, due to a drop in domestic steel demand and commercial coke sales.

The shares are down 3.2 percent at 35.50 rand. - Reuters
