Pakistani Taliban, disguised as policemen, have secured the relesae of more than 300 prisoners late on Monday night in Dera Ismail Khan. Many prisoners, four security personnel and two assailants were killed in the attack. At the time of the attack, the prison was housing 5000 prisoners.
Around 50-60 gunmen attacked the jail with bombs and guns before entering it. They detonated about 60 bombs inside the prison which caused the collapse of its wall. The assailants succeeded in freeing more than 300 inmates. The militants also blew up two transformers, thereby creating complete darkness.
The Tehreek-i-Taliban Pakistan (TTP) has claimed responisbility for the attack. The bombings triggered a gunfight between the militants and policemen which went on for hours. As the police could not control the situation, the local administration had to call in the military. The law enforcement agencies cordoned off the prison and surrounding areas before launching an operation.
Dera Ismail Khan is on the edge of Pakistan's tribal region of South Waziristan. The Pak army had launched a military operation against the Taliban militants in South Waziristan and flushed them out.
In April 2012, more than 100 militants of the Pakistani Taliban had brokeen into a prison in Bannu near North Waziristan tribal region, freeing nearly 400 prisoners.
