Updated from 1:53 p.m. EST with updated death toll in Algerian clash.By Paul Schemm and Karim Kebir ALGIERS, Algeria -- In a bloody finale, Algerian special forces stormed a natural gas complex in the Sahara desert on Saturday to end a standoff with Islamist extremists that left at least 23 hostages dead and killed all 32 militants involved, the Algerian government said. With few details emerging from the remote site in eastern Algeria, it was unclear whether anyone was rescued in the final operation, but the number of hostages killed on Saturday -- seven -- was how many the militants had said that morning they still had. The government described the toll as provisional and some foreigners remained unaccounted for. The siege at Ain Amenas transfixed the world after radical Islamists linked to al Qaeda stormed the complex, which contained hundreds of plant workers from all over the world, then held them hostage surrounded by the Algerian military and its attack helicopters for four tense days that were punctuated with gun battles and dramatic tales of escape. Algeria's response to the crisis was typical of its history in confronting terrorists, favoring military action over negotiation, which caused an international outcry from countries worried about their citizens. Algerian military forces twice assaulted the two areas where the hostages were being held with minimal apparent mediation -- first on Thursday, then on Saturday. "To avoid a bloody turn of events in response to the extreme danger of the situation, the army's special forces launched an intervention with efficiency and professionalism to neutralize the terrorist groups that were first trying to flee with the hostages and then blow up the gas facilities," Algeria's Interior Ministry said in a statement about the standoff. Immediately after the assault, French President Francois Hollande gave his backing to Algeria's tough tactics, saying they were "the most adapted response to the crisis."
