(CNN) -- The authorities who control Kosovo may have stolen organs from prisoners of war and political rivals when the Kosovo Liberation Army was fighting Serbian forces for control of the territory, European authorities allege in a new report.
"Numerous indications seem to confirm that... organs were removed from some prisoners... to be taken abroad for transplantation," according to a draft report from the Council of Europe.
And links between "criminal activity" and "certain KLA militia leaders... has continued, albeit in other forms, until today," the report charges.
Prime Minister Hashim Thaci of Kosovo is one of the founders of the Kosovo Liberation Army. The report names him as the "boss" of a prominent faction in the militia that "apparently wrested control" of "illicit criminal enterprises" from rivals across the border in Albania.
Kosovo's government called the report "defamatory" and "mendacious," saying the allegations "have been constructed to damage the image of Kosovo and the Kosovo Liberation Army".
On Thursday, the report will be debated by a committee of the Council of Europe, an organization with 47 member countries that seeks to promote democracy and human rights. The council's parliament plans to debate it in January.
It's based partially on investigations by European Union officials and written by Dick Marty for the Council of Europe's Committee on Legal Affairs and Human Rights.
The investigators have "made progress" toward "proving the existence of secret KLA places of detention in northern Albania where inhuman treatment and even murders are said to have been committed," Marty says.
Investigators are not getting enough cooperation from either Albania or Kosovo, the report adds.
Kosovo's majority population is ethnic Albanian. Serbs are the minority.
The KLA was backed by NATO bombing when it fought for independence from Serbia in the late 1990s. CNN
