Oil companies tighten Nigeria security as protests, job losses stoke tension
PORT HARCOURT/LAGOS: Oil companies have asked security services to tighten surveillance as violent anti-police brutality protests and the expected sacking of hundreds of workers worsen desperation in the region, industry sources told Reuters.

Already unemployment is above 40 per cent in Nigeria‘s energy regions and observers say further job losses could aggravate problems of pipeline tapping, illegal oil refining and pirate attacks.
