US military representatives trolled ISIS savagely on Tuesday after the Syrian Observatory for Human Rights reported that the group's leader, Abu Bakr al-Baghdadi, had been confirmed dead.
When asked to confirm whether the ISIS leader had died, a military representative told CBS News' Cami McCormick: "We strongly advise ISIS to implement a strong line of succession. It will be needed."
The latest wave of reports of Baghdadi's death come as ISIS's territory in Iraq and Syria shrinks and the group's remaining militants run out of places to hide.
On Sunday, the Iraqi government said the city of Mosul, where ISIS in 2014 declared its "caliphate," or territory, had been liberated.
The US has since 2014 led a coalition of 67 nations in training and equipping ground forces to fight ISIS and providing air support for those troops, but according to all official estimates, ISIS's days of controlling territory in Iraq and Syria are numbered.
