There is a video at the link above.  We don't have sufficient aircraft in place to attack their movement to contact at this time.  The air strikes have been hitting infrastructure targets mainly at this point.  As noted in a post below we are finally shipping some A-10s to the area that should be operational next month.  Those planes could attack the ISIL ground units.
