A complex attack by the Islamic State group against a prison in eastern Nangarhar province continued Monday and has killed at least 11 people, a local official said.
Another 42 people have been wounded in the gunbattle that began Sunday evening, said Zahir Adil, spokesman for the provincial health department. He said the toll was expected to rise.
The attack began when a suicide car bomb exploded at the entrance gate of the prison in Jalalabad, the capital of Nangarhar province. A number of assailants then opened fire on Afghan security forces. It wasn't clear how many assailants were involved
