Algerian Prime Minister Abdelmalek Sellal has said the 32 militants who took dozens of people hostage at In Amenas gas plant had “come from northern Mali”.
As many as 48 hostages – including foreigners – are thought to have died at the site near the town of In Amenas.
About 20 captives remain unaccounted for after the four-day siege, which ended on Sunday.
The militants said they took hostages in retaliation for French intervention against Islamists in Mali.
