The United States Central Intelligence Agency (CIA) and the Pentagon’s Joint Special Operations Command (JSOC) are carrying out a secret drone missile assassination program in Syria, the Washington Post reported late Tuesday.

The existence of the so-called targeted killing program has came to light in the wake of last month’s assassination of a British citizen identified as 21-year-old Junaid Hussein, a hacker who is described as a cyber expert for the Islamic State in Iraq and Syria (ISIS).
