Tributes have been paid today as oil companies marked the one year anniversary of the terrorist attack in Algeria which killed 40 people.
Al Qaeda gunmen stormed the In Amenas gas plant on January 16 last year, taking hundreds of oil workers and staff hostage in a three day siege.
The plant, operated by BP, Statoil and Sonatrach, restarted production last year but foreign workers have yet to return to the facility, situated more than 1000km southeast of Algiers.
BP staff held a minute’s silence at 11am today, to mark the loss of their four colleagues, while a memorial service was held at the same time by Statoil in Stavanger.
A coroner’s inquest is underway in the UK into the death of the three British workers killed in the attack, while a review by Statoil last September concluded security at the facility was not sufficient to withstand an attack.
