It is hoped that Libya will soon finalise a deal to free six foreign medics convicted of infecting hundreds of Libyan children with HIV.
All six were accused of deliberately infecting more than 400 children at a hospital in Benghazi.
Libya lifted death sentences against the medics last week but is now asking for normalised ties with the EU and is holding out for more foreign funds before it allows the foreigners to go home.
The EU insists the five Bulgarian nurses and Palestinian doctor are innocent and has been reluctant to pay compensation that could be interpreted as an admission of their guilt.
Last week a Libyan judicial council commuted the death sentences against the six to life imprisonment after the victims' families received a $330m settlement.
That opened the way for the nurses to return home under a 1984 prisoner exchange agreement.
Once in Bulgaria, they could be pardoned Bulgarian president Georgi Parvanov.
A senior EU official and France's first lady have been actively seeking their release.
EU External Relations Commissioner Benita Ferrero-Waldner, and the wife of French President Nicolas Sarkozy travelled to the north African state over the weekend.
