Plans to build a memorial at the site of a notorious concentration camp of the Bosnian war have been suspended after the main sponsor pulled out. Hundreds of Muslim and Croat prisoners were tortured and killed by Bosnian Serb guards during 1992 at the Omarska iron ore mine in northern Bosnia...Mittal Steel, recently bought the complex and was ready to erect a memorial...Mittal Steel said it was disappointed it had to abandon the plans for the memorial but...said it had become clear that many locals opposed the plans and under the circumstances they would be suspended...Many Bosnian Serbs say there should not even be a memorial. Many Muslims believe it should not be built until all the victims have been located and only then if the whole mine - which is currently working again - is used for the memorial site.
