Libya is preparing to submit a full declaration on its chemical weapons programmes to the United Nations.
The move is a part of the country’s efforts to rid itself of chemical weapons, as promised in a surprise announcement last December.
The declaration will be submitted by a Libyan envoy to the UN body overseeing the Chemical Weapons Convention.
The UN has praised Libya after it supervised the destruction of more than 3,000 empty chemical bombs on Thursday.
Libyan officials will arrive at the Organisation for the Prohibition of Chemical Weapons (OPCW) headquarters in The Hague on Friday morning to hand over a detailed declaration of chemical weapons programme.
This will list existing stocks of chemical agents and provide an inventory of production facilities and associated equipment.
This, in turn, will all have to be destroyed under the watchful eye of inspectors.
BBC defence correspondent Jonathan Marcus says Libya is thought to have had significant stocks of mustard agent and to have carried out research to produce the nerve agents sarin and soman.
Our correspondent says Libya’s first step in chemical disarmament was a decidedly low-tech affair – bulldozers were used to crush the casings of the unfilled chemical bombs.
The destruction was achieved ahead of schedule and the director general of the OPCW, Rogelio Pfirter, commented on the “swift and co-operative spirit of compliance on the part of the Libyan authorities”.
The Libyan example is an unusual one in the world of arms control, our correspondent says.
Last December, the Libyans revealed their intention to give up all weapons of mass destruction, following months of secret talks with British and US officials.
Nuclear inspectors from the OPCW’s sister organisation, the International Atomic Energy Agency (IAEA), have already been at work assessing Libya’s nuclear weapons programme, although this was less advanced than the country’s chemical weapons activities.
