A total of 37 foreigners and an Algerian died at a desert gas plant and five are still missing after a four-day hostage-taking coordinated by a Canadian gunman, Algerian Prime Minister Abdelmalek Sellal said yesterday.

Sellal also told a news conference that 29 Islamists had been killed in the siege, which Algerian forces ended by storming the plant on Saturday, and three were taken alive. Most of the gunmen were from various states of north and west Africa. With some bodies burned beyond recognition and Algerian forces still combing the sprawling site, some details were still unclear or at odds with figures from other governments.

The siege has shaken confidence in the security of Algeria’s vital energy industry and drawn attention to Islamist militancy across the Sahara, where France has sent troops to neighbouring Mali to fight rebels who have obtained weaponry from Libya.

Of the 38 dead captives, out of a total workforce of some 800 at the In Amenas gas facility, seven were still unidentified but assumed to be foreigners, Algerian Premier Sellal said.

Citizens of nine countries died, he said, among them seven Japanese, six Filipinos, two Romanians, an American, a Frenchman and four Britons. Britain said three Britons were dead and three plus a London-based Colombian were missing and believed dead.

Norway said the fate of five of its citizens was unclear; in addition to seven Japanese dead, Tokyo said three were missing.

An Algerian security source had earlier said that documents found on the bodies of two militants had identified them as Canadians: “A Canadian was among the militants. He was coordinating the attack,” Sellal said, adding that the raiders had threatened to blow up the gas installation.

That Canadian’s name was given only as Chedad. Algerian officials have also named other militants in recent days as having leadership roles among the attackers. Veteran Islamist Mokhtar Belmokhtar claimed responsibility on behalf of al-Qaeda.

In Ottawa, Canada’s foreign affairs department said it was seeking information, but referred to the possible involvement of only one Canadian.

The jihadists had planned the attack two months ago in neighbouring Mali, Sellal added.
