LONDON (Reuters) - British forensic experts have uncovered a mass grave in Kosovo containing the bodies of 50 people, including women and children, Foreign Secretary Robin Cook said on Thursday. Cook said the grave was the largest so far uncovered by the forensic team and reiterated Britain‘s call for Serb officials to be brought to justice for a campaign of ethnic cleansing against Kosovo Albanians. The bodies were found buried four metres beneath a rubbish dump in Ljubidza, six km (four miles) north of the town of Prizren. „We believe there are 50 bodies in the grave,“ Cook said after talks with Hashim Thaqi, political leader of the Kosovo Liberation Army (KLA). Before Wednesday‘s discovery the forensic team had already exhumed 280 bodies found in eight sites around Kosovo. Cook said many of them were children and one was only two years old. He said all the evidence gathered by the experts would be made available to an international war crimes tribunal which has already indicted Yugoslav President Slobodan Milosevic. „No country is more committed than Britain to bringing to justice those who carried out the atrocities which outraged the world and led to our action to make sure that Belgrade would not continue that repression,“ Cook told reporters in London. Britain was a leading hawk in the NATO alliance which bombed Yugoslavia for 11 weeks to stop a Serbian offensive against separatist Albanian guerrillas in Kosovo that had escalated into a campaign to expel the population and destroy their towns and villages. British officials said the grave at Ljubidza contained the bodies of a „considerable number“ of women and children. Work to exhume the corpses was expected to take several days.
