Bosnian Serb police have discovered what they say were two large primed bombs near the memorial centre for the Srebrenica massacre. Thousands of people are expected to gather there next week for a commemoration service marking the 10th anniversary of the killings. The police were said to have made the find following a tip-off from EU peace keepers.The devices were discovered in a former concrete factory near the memorial. Foreign dignitaries will join victims relatives for a ceremony there next Monday. A police spokesman said the bombs would have had “a huge destructive force.” The massacre, in which 8,000 muslim men and boys were killed by Bosnian Serb forces in 1995, remains a deeply emotive and controversial issue in the region. Leaders deemed ultimately responsible for the slaughter – Ratko Mladic and Radovan Karadzic – are still being sought by the international war crimes tribunal. A video linked to the massacre was shown recently at the trial of the former president of Serbia, Slobodan Milosevic. Several former paramilitaries were arrested by Serb authorities after the footage was aired.
