ISIS claimed responsibility for an attack Manbij that took place during the night of March 25-26. It comes just days after the declaration of the defeat of ISIS.
The Manbij Military Council announced it. “Terrorist attack on a roadblock at the entrance to Manbij was carried out at midnight around 12 p.m. on Wednesday night, after which seven militants carrying out their duties were martyred.”
It is an example of the kind of sleeper cell attacks Wladimir Van Wilgenburg has argued will increase.
