PRISTINA (AFP) - The European Union said Wednesday it was ready to probe Kosovo's prime minister Hashim Thaci over accusations he was involved in organ-trafficking and other crimes in the aftermath of the 1998-99 war with Serbia. The report, by Swiss Council of Europe deputy Dick Marty, accuses Thaci of being in charge of a group within the ethnic-Albanian guerrilla Kosovo Liberation Army (KLA) that set up a network of unofficial prisons in Albania. The report alleges that one of Thaci's allies operated a ring for the "forcible extraction of human organs for the purposes of trafficking" from prisoners, mainly Serbs. In Pristina, the government of Thaci dismissed the report late Tuesday as "fabrications" designed to smear the country's leaders. Maja Kocijancic, spokeswoman for EU foreign policy chief Catherine Ashton, said in Brussels that "we take allegations on war crimes and organised crime extremely seriously. "We have seen the report and if the rapporteur, Mr. Marty, has any concrete evidence we invite him to bring this forward to the relevant authorities," including the EU's police and justice mission EULEX, she said. EULEX is a special EU rule of law mission in Kosovo (EULEX) which has the mandate to try cases that the Kosovo judiciary cannot or will not handle because of their sensitive nature like war crimes and corruption claims. Top human rights watchdog Amnesty International called on the EU "to open an immediate investigation" into Thaci's alleged involvement in the case. "The families of the Serbs, Roma and Albanians abducted after the war have waited too long for justice. They deserve to know their relatives' fate," said Nicolas Beger of the Amnesty International in the statement. Amnesty said it has called for "investigations" into the fate of those abducted after the conflict. But the international community "sacrificed some important principles of justice and chose not to investigate post-war abductions, political killings and other allegations against Thaci and KLA in order to promote short-term stability," the group said. And Belgrade, which does not recognise Kosovo's 2008 declaration of independence from Serbia or Thaci's government, was quick to question if he could remain on as prime minister. "I do not know what future that person has, if one takes into account the Council of Europe report," Serbian Foreign Minister Vuk Jeremic said following talks with his Russian counterpart Sergei Lavrov in Moscow. In Kosovo, media published only the main conclusions of the report and the government's statement without commenting.One independent journalist, who asked not to be named because of the taboo surrounding the topic, said it was a serious blow for Thaci, the hardest he had ever received. "He might survive the hit locally but I can hardly imagine Western statesmen from now on posing with him and smiling for the camera," he told AFP. Migjen Kelmendi, the head of Kosovo's independent Rrokum TV, has reported extensively on the accusations of organ trafficking, even screening a special documentary made by Serbia's independent B92 broadcaster. "I've been studying the accusations of organ harvesting but I still haven't seen any proof," he stressed. Marty's report says the trafficking and other criminal enterprises were controlled by the so-called Drenica group within the KLA after the war ended in Kosovo in 1999. "We found that the Drenica group has as its chief the renowned political operator and perhaps most internationally recognised personality of the KLA, Hashim Thaci," the report said. It added that intelligence reports commonly identified Thaci "as one of the most dangerous of the KLA's criminal bosses" who also controls the trade in heroin and other narcotics.
