This document appears to be a set of instructions to Abu Usama, who is located in Anbar, `Iraq, regarding the situation with a cell, or group. The writer, “Your brother”, seems to imply that Abu Usama is treating his cell too soft, and needs to toughen up. The writer indicates that Abu Usama must stop killing people unless they are spies, members of the military, or police officers. The writer warns that if that type of activity continues, the people will be fighting them (i.e. his cell or group) in the streets. The author of the letter orders Abu Usama to see him immediately.
