Secretary of State Hillary Rodham Clinton is telling Algeria to do everything possible to protect hostages as it seeks to free them from militants at a natural gas complex in the Sahara.
Clinton says that in her conversation Friday with Algerian Prime Minister Abdelmalek Sellal, she underscored that "the utmost care must be taken to preserve innocent life."
The State Department says Americans are still being held hostage, and world leaders have criticized Algeria for its handling of the attack.
Clinton did not criticize the North African country.
The attack, she says, was an "act of terror." She also vows greater U. S.-Algerian counterterrorism cooperation in future.
