Six medical workers accused by Libya of infecting children with the virus that causes AIDS are describing to Bulgarian officials Friday how they were tortured in Libya.
Bulgarian authorities are questioning the workers in Sofia as part of an ongoing investigation.
Prosecutors in the Bulgarian capital say they are preparing to bring torture charges against several Libyan police officers.
Libya had charged the five Bulgarian nurses and one Palestinian doctor with deliberately infecting more than 400 Libyan children with HIV, but AIDS experts blame unclean conditions at a Libyan hospital for the infections.
The medical workers had been sentenced in Libya to life in prison. But they claimed they were shocked with electricity and beaten into confessing to the charges.
The son of Libyan leader Moammar Gadhafi, Seif al-Islam Gadhafi, admitted Thursday during a television interview that the six had been tortured.
They were released last month after spending eight years in a Libyan prison. They were pardoned when they returned to Bulgaria.
