JERUSALEM (Ma'an) -- Sheikh Raed Salah, a leader of the Palestinian community inside Israel, will be released from prison Sunday after serving five months for assaulting a police officer, a charge he denies.

Salah's attorney Zahi Nijiadat said a celebration will be held in the city of Umm Al-Fahm in honor of the release of the Islamic Movement in Israel.

Kamal Al-Kahtib, the deputy leader of the Islamic Movement said, "We believe that the imprisonment was unfair, because the arrest was carried out for political reasons. It had nothing to do with justice nor with the details of the fabricated charges."

"The aim was to pressure Salah to prevent him from communicating with the Palestinians specifically on their two main issues Jerusalem and Al-Aqsa mosque," he added.

Raed turned himself in to police in July after being convicted on charges of participating in a riot and assaulting a police officer.

Salah also participated in the Gaza aid flotilla in May which ended in a raid by Israeli forces that left nine Turkish activists dead.
