Seif al-Islam told the Bulgarian newspaper "24 Hours" today that the nurses' trial was "unfair" and that he has proposed a plan to free the nurses in exchange for financial compensation to the victims' families.
Al-Islam said he had discussed the plan with Bulgarian and EU officials. He gave no other details.
The nurses and a Palestinian doctor were sentenced in December for having infected 426 children at a Libyan hospital with blood tainted by the HIV virus, which causes AIDS. More than 50 of the children have died.
EU and Bulgarian officials have claimed the defendants are innocent and called for their release.
