As I'm extremely uneducated in terms of all this western anti-whatever propaganda for me it actually took to google what exactly is the Islamic State, but anyway headline appears to be correct, as, according to Wikipedia "Since June 2014 it calls itself the Islamic State (IS), a name widely rejected by non-members". So indeed it would be incorrect to call it ISIS or ISIL or whatever else.
