In this image made from video, a group of people believed to be hostages kneel in the sand with their hands in the air at an unknown location in Algeria. Algerian de-mining teams were scouring a gas refinery on Sunday, Jan. 20, 2013 that was the scene of a bloody four-day standoff, searching for explosive traps left by the Islamist militants who took dozens of foreigners hostage. The siege left at least 23 captives dead, and the American government warned that there were credible threats of more kidnapping attempts on Westerners. (AP Photo/Ennahar TV) ALGERIA OUT, TV OUT
