At least 21 people have been killed so far in ongoing fighting between Afghan security forces and terrorists who raided a jail overnight.
The attack has been claimed by ISIS.
Among the dead were prisoners as well as civilians, prison guards and Afghan security personnel, Attaullah Khogy, a spokesman for the governor of Nangarhar province, told Al Jazeera.
Around 43 people have been wounded in the attack in the provincial capital Jalalabad that began late on Sunday when a suicide bomber slammed his explosive-laden vehicle into the prison entrance.
Three terrorists have been killed so far.
Afghan officials said the death toll could rise.
