A general view shows an oil installation on the outskirts of In Amenas, deep in the Sahara near the Libyan border, on January 18, 2013. Islamist hostage-takers at a nearby gas field in the area, more than 1,300 kms southeast of the capital Algiers, demanded a prisoner swap and an end to the French military campaign in Mali, a report said, while 30 foreigners were reported still missing in the worst international hostage drama for years.
