JERUSALEM (JTA) — Israeli Arabs marched in the northern Israeli community of Sakhnin to mark the 12th anniversary of the death of 13 Arab protesters in riots at the start of the second Palestinian intifada.

The several thousand protesters marched Oct. 1, carrying Palestinian flags and signs reading: “We shall not forgive the killers,” according to the Jerusalem Post.

The protesters also called for the prosecution of the Israeli policemen who shot dead the Arab protesters 12 years ago.

Protests also took place in Nazereth, Kfar Kana, Arabeh, Umm al-Fahm, and Rahat, and at the cemeteries where the dead Arab protesters are buried.
