Authorities in Khagrachhari have imposed Section 144 indefinitely following violent clashes between two rival hill-dwelling groups. Since Sunday morning, major roads in the town have seen little activity, with shops largely closed and public life paralyzed. Officials said the restriction was necessary to prevent further deterioration of law and order and to protect lives and property. The unrest began Saturday when Jumma student groups staged blockades demanding justice for sexual violence against women in the hills. The protest spiraled into confrontations, prompting the sweeping restrictions.
