Nations scramble to account for missing after Algeria hostage crisis

Freed Norwegian hostage Oddvar Birkedal is escorted at a police station in Amenas, Algeria, on Saturday.

The hostage crisis in eastern Algeria is over, but the questions remain.

Among them, exactly how many people are unaccounted for at a remote natural gas facility after three days of chaos that ended saturday , leaving 23 hostages and dozens of Islamist militants dead.

Some 685 Algerian workers and 107 foreigners were freed, the Algerian Interior Ministry said.

"Search efforts are ongoing at the gas installation, looking for more possible victims. I fear the numbers will be updated with more victims later today when the search operation is expected to end," said Mohammed Said, the Algerian communication minister.

The attackers are members of six nationalities and include Arabs, Africans and people from other non-African nations, he told state-run Radio Algeria.

Eleven of the former hostages -- including several British citizens -- have received medical treatment and psychological counseling from the U.S. military at a U.S. naval base in Sigonella, Italy, a U.S. official said Sunday. The hostages were brought to the base from Algeria on Friday, the official said, and are being flown back to their home countries as their conditions warrant. The remains of one American hostage were also brought to the base, the official said
