Bangladesh's government is again deploying troops to stop fighting between ethnic groups in the Chittagong Hill Tracts.
Bangladeshi troops were sent to the town of Khagrachhari after 30 people were injured in Tuesday's clashes involving Bengali Muslim settlers and Buddhist tribespeople. Officials say about 100 houses were set ablaze in the fighting.
Bangladeshi authorities have imposed a ban on public gatherings in Khagrachhari to restore order.
The violence erupted after tribal activists from the United People's Democratic Front blocked roads to protest the killing of two tribal people in clashes with Bengali settlers on Saturday.
Earlier clashes in the neighboring town of Baghaichhari also resulted in around 100 homes being torched and prompted the government to deploy troops.
