Description:Al Qaeda-affiliated militants man a checkpoint in southern Yemen. The Ansar al-Sharia group on Sunday freed 73 Yemeni soldiers it had captured in a major assault on the city of Zinjibar last month in which more than 100 other conscripts were killed. The militant group was threatening to harm the soldiers unless fellow Islamist fighters were released from jail. But in a statement, Ansar al-Sharia said it had released the soldiers out of respect for the mediators.(1:07)
