Algeria has strongly denied reports stating that Colonel Gaddafi and his sons may have entered the country on Friday in a convoy of cars.
The Foreign Ministry says Algeria has been the victim of a stream of false information for months.
The official Egyptian news agency Mena quoted a rebel source as saying that Gaddafi may have been in a convoy of armour-plated Mercedes cars seen crossing the border to Ghadames.
But one Algerian journalist believes it is plausible that Algeria might take in Gaddafi.
