Some of the tiny minority of extremists seem to have been operating a camp in the Libyan desert. From the [1] New York Times, with thanks to Jeffrey Imm:

PARIS, July 4 — Libyan forces have discovered a terrorist camp with ties to Al Qaeda in the country's southern desert, a French newspaper reported Sunday. The report did not say whether the camp was active or abandoned when it was found 10 days ago.

The newspaper, Le Journal du Dimanche, quoted European antiterrorism officials as saying that the camp, thought to be used by the Salafist Group for Preaching and Combat, was near the border with Chad not far from the region where Chadian rebels are holding one of the terrorist group's most senior members, Amari Saifi, known as Al Para.
