Algeria's special forces stormed a natural gas complex in the middle of the Sahara desert on Saturday in a "final assault" aimed at ending a four-day-old hostage crisis, the state news agency reported. It said 11 militants and seven hostages were killed. The report, quoting a security source, didn't say whether any hostages or militants remained alive, and it didn't give the nationalities of the dead. It said the army was forced to intervene after a fire broke out in the plant.
