The longest serving Palestinian prisoner being held under administrative detention in the Zionist entity prison was released on Sunday

The longest serving Palestinian prisoner being held under administrative detention in the Zionist entity prison was released on Sunday, a Hamas statement said.

Adnan Asfour, 50, a senior figure within the resistance movement, was detained by Israeli occupation forces on March 9, 2009, and has been imprisoned for a total of six years during his life, having been arrested on 16 separate occasions.

He had been held by Zionist authorities for over three years without being charged for a crime, director of Ahrar center for prisoners Fuad al-Khafsh said Saturday.

He participated in a mass hunger strike campaign by prisoners in April, when nearly 2,000 Palestinians in Israeli jails refused to eat in protest against prison conditions and administrative detention, al-Khafsh added.

There are at least 300 people currently being held under administrative detention, according to Addameer prisoners group. The administrative detention policy states that prisoners can be held without formal charges for renewable periods of six months. Defendants and their lawyers are not given access to the evidence used to imprison them, according to Maan news agency.
