ALGIERS, June 28 (Reuters) - Foreign oil workers arereturning to work at Algeria's In Amenas gas plant nearly a yearand a half after the Islamist militant attack there that killed40 people, a source at Algerian state energy company Sonatrachsaid on Saturday.
"Twelve expatriate workers are already at the gas facilityand more are expected progressively," the source said withoutgiving details on their nationalities.
