Mohammed Hadia, a government committee member, said IS fighters are looking for members of the Frejani tribe to kill or detain. The tribe fought alongside an Islamist group that refused to pledge allegiance to the IS affiliate, which then laid a siege on the neighborhood for days.
Alaa Frejani said his family in Sirte saw IS militants using loudspeakers to warn residents of neighboring areas they would face a similar fate if they cross them.
