During the occupation of Iraq U.S. intelligence and military services contracted CACI International Inc, a U.S. company in Virginia, to provide "intelligence services" in Abu Ghraib prison near Baghdad. CACI employees were directly involved in torturing Iraqi prisoners.
The U.S. army recently contracted CACI for "intelligence analysis services" in Syria. The Syrian government has not invited or otherwise allowed U.S. military or its contractors to enter the country. Any such activities infringe on Syria's sovereignty and are thereby in violation of international law.
The re-engagement of such a controversial company for services in the area boosts the recruitment appeal of the Islamic State.
A recent U.S. Department of Defense Contracts Press Announcement (Release No: CR-143-16, July 27, 2016) lists under the rubric "Army":
"Six3 Intelligence Solutions Inc., McLean, Virginia, was awarded a $ 9,578,964 modification (P00001) to contract W564KV-16-C-0058 for intelligence analysis services. Work will be performed in Germany, Italy, and Syria, with an estimated completion date of June 29, 2017."
