Unidentified gunmen have killed seven passengers at a bus terminal in southwest Pakistan, police said, and another 12 were injured. Baluchistan is home to a small separatist movement that often targets Pakistanis from other parts of the country living there. Many non-Baluch have left as a result. (AP Photo/Arshad Butt)
