Western couple held in Afghanistan

The family of a pregnant American woman who went missing in Afghanistan in late 2012 with her Canadian husband received two videos last year in which the couple asked the U.S. government to help free them and their child from Taliban captors, The Associated Press has learned.

The videos offer the first and only clues about what happened to Caitlan Coleman and Joshua Boyle after they lost touch with their families 20 months ago while traveling in a mountainous region near the capital, Kabul. U.S. law enforcement officials investigating the couple's disappearance consider the videos authentic but say they hold limited investigative value since it's not clear when or where they were made.
