ISIS has a navy? The US is sinking it
While Iraq is nearly entirely land-locked, the Tigris and Euphrates rivers that cross that country are navigable, and ISIS has been using watercraft for a variety of purposes, including transporting fighters and conducting improvised explosive attacks.\
The US-led anti-ISIS coalition provided CNN with video of a September 10 airstrike against an ISIS tactical unit aboard a boat near Bayji, Iraq.
Barges, skiffs and motorized watercraft have been observed operating along the Tigris and Euphrates rivers for the purpose of ferrying ISIS fighters and equipment across the rivers, Operation Inherent Resolve spokesperson Col. Joseph Scrocca told CNN, adding that it happens often when anti-ISIS Iraqi troops control the area’s bridges. Coalition bombs have also targeted bridges used by ISIS, thereby further necessitating the terror group’s reliance on boats.
