They only fight at night when the darkness gives them cover.  By working in a different area of the city each night, no one knows where or when they’ll strike.  Their mission?  Killing ISIS militants, and those who support them, any way they can.

Mosul’s Shadow Ninjas are vigilante groups who’ve taken up the fight against ISIS.  They’ll use snipers or roadside bombs and strangling or stabbing their prey works too.  While ISIS is trying to eliminate them, locals say these rogue warriors are making an impact and causing the Islamic extremist group to change the way they operate.  Men in Mosul have been ordered to grow beards so the militants can blend in and ISIS militants are driving unmarked cars because of the roadside bombs.
