The Islamic State of Iraq and the Levant (ISIL) is the name that a terrorist group gave Iraq and parts of Syria after a forced invasion of the territory. ISIL is an armed terrorist organization that attacks U.S. military operations in Iraq. The history of ISIL is said to be rooted in al-Qaeda terrorism as early as 1999. After the Syrian crisis of 2011, ISIL started to gain traction in the region. Among the main groups that have been targeted by ISIL are the Yazidi Kurds. ISIL separated from al-Qaeda in 2014 and claims to be active in almost 15 countries.
