Since then, Algeria's government has kept a tight grip on information about the siege.
Clinton stressed that American officials would stay in close contact with their Algerian counterparts. Sellal, she said, made clear that the Algerian operation against the militants "was still ongoing, that the situation remained fluid, that the hostages remain in danger in a number of instances."
Speaking beside Japan's new foreign minister, Fumio Kishida, Clinton said the crisis underscored the threat posed by extremists in North Africa, where al-Qaida-linked militants have seized control of half of Mali and plunged the country into civil war. She vowed to enhance U.S. work with Algeria and other countries in the region to combat terrorists even after the hostage situation ends.
"It is absolutely essential that as we work to resolve this particular terrible situation, we continue to broaden and deepen our counterterrorism cooperation," Clinton said. "We will not rest until we do as much as we can ... to restore security to this vital region, and to bring those who would terrorize and kill innocent people to justice."
