Algerian state news agency APS said Thursday that the military operation launched to free hostages at a remote desert gas facility in the country has ended. Earlier Thursday the U.S. State Department called the situation “extremely fluid” and claimed it was working with “affected nations” to resolve the conflict. It is now being reported 30 hostages were killed in the assault. The Islamist militants were demanding an end to the French-led military invasion of Mali. Officials say five Americans escaped from Algeria terrorists, and are now safe. Secretary of State Hillary Clinton has ordered a review of security for diplomats in the country.
