Sheikh Raed Salah, a leader of the Palestinian community inside Israel, has been released from prison Sunday after serving five months, media confirmed.
Speaking briefly to his supporters, Salah stressed he was the victim of political persecution for his defence of the Al-Aqsa mosque compound in Jerusalem.
Salah's attorney Zahi Nijiadat told Palestinian news agency, 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 told Maan news agency, "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 protest and allegedly 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.
Salah is a resident of Umm al-Fahm, the second biggest Arab city in Israel and the centre of the Islamic Movement.
The Islamic Movement in Israel was founded in 1971 with the aim of advocating Islam among Palestinians.
