KIEV, Nov. 19 - Metinvest, Ukraine's biggest iron and steel holding, has rejected reports it was buying Slovakia-based U.S. Steel Kosice.

"We haven't bought it," an official Metinvest representative told Interfax, without commenting further.

U.S. Steel has also denied Slovak press reports that U.S. Steel Kosice was being sold to Metinvest.

Russia's Evraz told Interfax that it would not comment on rumors.

Slovakia's Hospodarske noviny (HN) newspaper said on Saturday that Metinvest was showing an interest in the acquisition of Slovakia-based U.S. Steel Kosice.
