Six inmates were killed in a clash between two groups of inmates in Jamalpur District Jail, authorities said on Friday, reports UNB.
Moreover, district jailer and seven prison guards were injured in the clash on Thursday afternoon.

Abu Fattah, jailer of the district jail, said two groups of the inmates locked into clashes inside the jail on Thursday afternoon. Six of them died in the clashes.
The jailer, however, didn't elaborate how they died.
After bringing the situation under control, the inmates beat the jailer, held him captive and tried to escape from the jail, he said.
The inmates vandalised two buildings within the prison, the jailer's office, and one of the main gates. They also set fire to several parts of the facility, taking 14 prison guards hostage in the process, he said.
At one stage, the prison guards responded by firing warning shots to regain control of the situation, the jailer said.
In response to the crisis, Army, Rapid Action Battalion (RAB), police, and fire service personnel were deployed in the jail to restore order. The hostages were released later that night, and by 3am, prison authorities had regained full control of the facility, jailer Fattah said.
