Statoil reveals chronic weak security at Algerian plant before deadly attack

OSLO (Reuters) - Oil major Statoil missed multiple warning signs and failed to foresee or prepare for incidents like January's deadly attack at an Algerian plant in January, an internal company investigation said, painting a picture of chronic security problems at the site.

Some 40 workers, including five Statoil workers, were killed when Islamist militants raided the In Amenas gas plant deep in the Sahara desert, near the Libyan border, taking foreign workers hostage in a four-day siege that ended when Algerian forces stormed the plant.
