A Saudi Arabian newspaper has published a list of 12 traits to look for in people who might sympathise with Islamic State (Isis) terrorists.
The first group of markers indicates whether someone is still in the "stage of doubt", while the second group contains traits found in people who are in "the state of certainty".
IS controls large swathes of Syria, Iraq and Libya and its insurgency has caused the death of thousands.
The group has become famous worldwide for its brutal executions and attacks , often captured on video and used as part of its propaganda machine to recruit members.
Among other things, IS is known for using child soldiers, persecuting non-Muslim and non-Sunni groups and enslaving thousands of women and girls from the Yazidi ethno-religious group.
