The miniseries will be based on Joby Warrick's book Black Flags: The Rise Of ISIS. The American Sniper star will serve as an executive producer alongside Phillips.

Black Flags will centre on the rise of the terrorist group and the intelligence organisations attempting to disband the group.

Author Gregg Hurwitz is writing the adaptation and executive producing and Tim Van Patten will direct.

The miniseries news follows a string of ISIS attacks around the world, including a terrorist attack in Nice, France in July (16), when 84 people were killed after a truck drove through a crowd watching fireworks at the Promenade des Anglais.
