ALGIERS, Algeria (AP) — A deadly Algerian military raid to free hostages from at least 10 countries and wipe out their Islamist militant captors moved closer to the heart of the natural gas complex on Friday, the government news service said.
A total of 18 militants were killed and the plant's living quarters were secured, according to the news agency, which cited security officials. Dozens of energy workers remained unaccounted for after the Algerian military's initial claim that the assault at the remote desert facility was over late Thursday.
Algeria's government has kept a tight grip on information, but it was clear that the militant assault that began Wednesday has killed at least six people from the factory — and perhaps many more.
Workers kidnapped by the militants came from around the world — Americans, Britons, French, Norwegians, Romanians, Malaysians, Japanese, Algerians. Leaders on Friday expressed strong concerns about how Algeria was handing the situation and its apparent reluctance to communicate.
British Prime Minister David Cameron went before the House of Commons on Friday to provide an update, seeming frustrated that Britain was not told about the military operation despite having "urged we be consulted."
Terrorized hostages from Ireland and Norway trickled out of the Ain Amenas plant, 800 miles (1,300 kilometers) south of Algiers, the capital. BP, which jointly operates the plant, said it had begun to evacuate employees from Algeria.
"This is a large and complex site and they are still pursuing terrorists and possibly some of the hostages," Cameron said. He told lawmakers the situation remained fluid and dangerous, saying "part of the threat has been eliminated in one part of the site, a threat still remains in another part."
Algeria's army-dominated government, hardened by decades of fighting Islamist militants, shrugged aside foreign offers of help and drove ahead alone.
On Friday, Algeria's ambassador to Japan was summoned and told that Japan demanded that Algeria prioritize hostages' lives and cooperate more closely.
The U.S. government sent an unmanned surveillance drone to the BP-operated site, near the border with Libya, but it could do little more than watch Thursday's military intervention. British intelligence and security officials were on the ground in Algeria's capital but were not at the installation, said a British official who spoke on condition of anonymity because he was not authorized to speak to reporters.
A U.S. official said while some Americans escaped, other Americans were either still held or unaccounted for. Defense Secretary Leon Panetta was briefed early Friday, according to a senior defense official, who offered no other details because "we view it as a sensitive, ongoing situation." The officials spoke on condition of anonymity because they authorized to discuss the matter publicly.
With the hostage drama entering its second day Thursday, Algerian security forces moved in, first with helicopter fire and then special forces, according to diplomats, a website close to the militants, and an Algerian security official. The government said it was forced to intervene because the militants were being stubborn and wanted to flee with the hostages.
Militants claimed 35 hostages died when the military helicopters opened fire as they were transporting hostages from the living quarters to the main factory area where other workers were being held.
The group — led by a Mali-based al-Qaida offshoot known as the Masked Brigade — suffered losses in Thursday's military assault — but garnered a global audience.
Even violence-scarred Algerians were stunned by the brazen hostage-taking Wednesday, the biggest in northern Africa in years and the first to include Americans as targets. Mass fighting in the 1990s had largely spared the lucrative oil and gas industry that gives Algeria its economic independence and regional weight.
The remote location is extremely hard to reach and was surrounded by Algerian security forces — who, like the militants, are inclined to advertise their successes and minimize their failures.
"An important number of hostages were freed and an important number of terrorists were eliminated, and we regret the few dead and wounded," Algeria's communications minister, Mohand Said Oubelaid, told national media on Thursday, adding that the "terrorists are multinational," coming from several different countries with the goal of "destabilizing Algeria, embroiling it in the Mali conflict and damaging its natural gas infrastructure."
The official news agency said four hostages were killed in Thursday's operation, two Britons and two Filipinos. Two others, a Briton and an Algerian, died Wednesday in the initial militant ambush on a bus ferrying foreign workers to an airport. Citing hospital officials, the APS news agency said six Algerians and seven foreigners were injured.
APS said some 600 local workers were safely freed in the raid — but many of those were reportedly released the day before by the militants themselves.
A spokesman for the Masked Brigade told the Nouakchott Information Agency in Mauritania that only seven hostages survived.
President Barack Obama and Cameron spoke on the phone to share their confusion. White House Press Secretary Jay Carney said the Obama administration was "seeking clarity from the government of Algeria."
BP, the Norwegian company Statoil and the Algerian state oil company Sonatrach, operate the gas field and a Japanese company, JGC Corp, provides services for the facility.
One Irish hostage managed to escape: electrician Stephen McFaul, who'd worked in North Africa's oil and natural gas fields off and on for 15 years. His family said the militants let hostages call their families to press the kidnappers' demands.
"He phoned me at 9 o'clock to say al-Qaida were holding him, kidnapped, and to contact the Irish government, for they wanted publicity. Nightmare, so it was. Never want to do it again. He'll not be back! He'll take a job here in Belfast like the rest of us," said his mother, Marie.
Dylan, McFaul's 13-year-old son, started crying as he talked to Ulster Television. "I feel over the moon, just really excited. I just can't wait for him to get home," he said.
At least one Filipino managed to escape and was slightly injured.
Algerian Interior Minister Daho Ould Kabila said the 20-odd militants entered the country from nearby Libya in three vehicles, in an operation commanded by extremist mastermind Moktar Belmoktar, who is normally based in Mali.
The militants made it clear that their attack was in revenge for the French intervention against Islamists who have taken over large parts of neighboring Mali. France has encountered fierce resistance from the extremist groups in Mali and failed to persuade many Western allies to join in the actual combat.
