Abstract

This piece is the first in a brief series of publications that examine activity by the Islamic State of Iraq and al-Sham in Syria and Iraq. ISIS is active on both sides of the border, executing complex attacks in Deir ez-Zour and organizing local governance efforts, while carrying out a well-organized campaign in Iraq. Upcoming releases from ISW will examine these issues in greater detail, exploring the non-military activities that ISIS publicizes in Syria, and comparing two “annual reports” released by the groups describing their “progress” in Iraq.
