At approximately 1100 Hours Local Time six Peace Corps volunteers have been verified as abducted by a terrorist organization hostile to the United States government and it's citizens. This organization is demanding the withdrawal from all US military, diplomatic and corporate presence from Calstinopa within 24 hours or they will execute all of the hostages.
Trajeto de Righteous is well known for it's drug smuggling and money laundering, as well as allowing members of Al Queda and other terrorist groups to use their facilities in order to train or gain medical care.

Two US Army Ranger teams present at the US Embassy are to be tasked for this mission, and authorization for lethal force has been granted.
