During the current operation to free Mosul from ISIS, a local radio station did some interviews with citizens of the city. One man told the radio station that he planned to drink some alcohol then get some shampoo to wash off the filth of ISIS. ISIS found out about it and kidnapped the man.
They made a video of the unusual execution but it’s not currently available. There are a couple of pictures that shows ISIS drowning the man in water and shampoo.
Currently, about a third of Mosul has been freed from the grips of ISIS. Iraq has sent in 30,000 troops to liberate the city. Despite the manpower it is expected to take months fefore the entire city is free.
