Sneberg was the last missing Statoil employee after the terror attack at In Amenas on 16 January.

“It is with deep sorrow that we have received the news today that Victor Sneberg, our country manager in Algeria, is among those who lost their lives in the terror attack at In Amenas,” says chief executive Helge Lund.

“Five friends and colleagues who were going about their work for Statoil will never return to their loved ones. They represented the very best of our company. Our thoughts and deepest compassion go first and foremost to the families, friends and colleagues who have lost those dear to them. Everyone in Statoil shares their grief. In the time ahead those most affected will need our support.”

The four who have previously been confirmed dead and who were brought home to Norway on 30 January are Tore Bech (58), Hans M Bjone (55), Thomas Snekkevik (35) and Alf Vik (43).

A mourning ceremony will be held in Haakon’s Hall in Bergen, Norway, on Monday 4 February.
