According to the BBC, there were 1,793 prisoners in the jail at the time of the attack. Most of them Taliban and IS fighters, a Security source told the AFP News Agency. Taliban had denied its involvement in the incident. However, Afghanistan’s Interior Minister Massoud Andarabi, said they had “solid intelligence” that the attack was designed by a local Taliban ‘commander’ in the Province adds New York Times. “Shahab Almahajir, the newly appointed leader of Islamic State of Khorasan Province, or IS-KP, is a Haqqani member,” Mr. Andrabi said. A senior Afghan official, speaking on the condition of anonymity, said that only a third of the prison’s population of about 1,800 included IS loyalists. The rest were split among Taliban prisoners and criminals. All of them got a chance to break free, at least for a while.
