Twelve Algerian and foreign workers have been killed since Algerian special forces began an assault against the kidnappers, the state news agency reported, citing an unnamed security official. It was the highest civilian death toll Algerian officials have provided in the aftermath of the assault, which freed captives and killed kidnappers but also left some hostages dead.
Previous estimates of the foreign casualties have ranged from 4 to 35.
The Algerian news agency said that the country’s special forces were still seeking to reach a “peaceful solution” with the remnants of a “terrorist group” that was still holding hostages in the refinery area of the gas field in remote eastern Algeria. It also gave a new sense of how many people may have been at the facility when the militants seized it on Wednesday, asserting that nearly 650 had managed to leave the site since then, including 573 Algerians and most of the 132 foreigners it said had been abducted.
But that still left many people unaccounted for, adding to the global concern about the fate of the hostages, who come from as many as 10 different nations.
In Washington, the State Department spokeswoman, Victoria Nuland, said that not all Americans had been freed and that Secretary of State Hillary Rodham Clinton had spoken for the third consecutive day by telephone with top Algerian leaders about American concerns for their safety.
“We have American hostages,” Ms. Nuland told reporters, offering the government’s first update on what is known about the Americans since officials confirmed on Thursday that seven or eight Americans had been inside the gas-field complex.
Ms. Nuland also said the United States would not consider a reported offer made by the kidnappers to exchange two Americans for two prominent figures imprisoned in the United States — Omar Abdel Rahman, a sheik convicted of plotting to bomb New York landmarks, and Aafia Siddiqui, a Pakistani woman convicted of shooting two American soldiers in Afghanistan. It was impossible to confirm that offer, which was reported by the Washington-based SITE Intelligence Group, a service that tracks jihadist activity on the Internet.
Intensifying the uncertainties, a spokesman for the militants, who belong to a group called Al Mulathameen, said Friday that they planned further attacks in Algeria, according to a report by the Mauritanian news agency ANI, which maintains frequent contact with militant groups in the region. The spokesman called upon Algerians to “keep away from the installations of foreign companies, because we will suddenly attack where no one would expect it,” ANI reported.
A Pentagon official said an Air Force C-130 had left Algeria for an unidentified base in Europe, carrying a number of the rescued hostages but no Americans. The official said a second, larger evacuation plane, a C-17, was still on the ground in Algeria, and it was unclear how many rescued hostages would be boarded or when it would depart.
A separate hostage situation of sorts appeared to be evolving at a village in Mali, the neighboring country where a French military intervention to stop radical Islamists may have been the catalyst for the Algerian gas-field seizure by the Al Mulathameen group.
A senior French official in Paris said Malian Islamist fighters, threatened by French and Malian soldiers, had occupied the village, Diabaly, and were threatening to use residents as human shields if attacked.
“We do not want a blood bath,” the French official said, and the troop commanders had chosen not to engage so far in house-to-house fighting.
The Algerian military operation at the gas field began on Thursday without consultation with the foreign governments whose citizens worked at the gas field facility. It has been marked by a fog of conflicting reports, compounded by the remoteness of the facility, near a town called In Amenas hundreds of miles across the desert from the Algerian capital, Algiers, and close to the Libyan border.
Algeria’s state radio, citing an official source, reported on Friday that 18 militants had been killed, the first precise death count offered by state media. The state news agency also suggested that hundreds of civilians “had been freed,” though many of the employees inside the sprawling facility may have simply been on site at the time of the militant assault and were not necessarily being held by the kidnappers.
