Nearly 400 prisoners have escaped from a prison in Pakistan

After a prison in Pakistan was attacked by Islamist militants, 384 of the 944 prisoners in the facility escaped.

The prison is located is Bannu, a town in Khyber Pakhtunkhwa, an area known for a heavy militant presence, BBC said.

Iftikhar Khan, a senior police officer, said that four prison officials were wounded during the attack, which lasted longer than two hours, CNN said.

Minister of Khyber-Pakhtunkhwa province, Mian Iftikhar Hussain, said that at least 20 of the escaped prisoners are very dangerous and that one was on death row for attempting to kill ex-President Pervez Musharraf, BBC said.

The attack, done by Pakistan's Taliban, apparently aimed to free a senior Taliban commander buf prison records were destroyed during the attack and officials have had trouble verifying the names of those who escaped, CNN said.
